Question 2 of 10 · Graph linear equations
No calculatorFill in
The table lists points on the graph of y = 4x - 3. Complete the table.
x
-2
-1
0
2
y
-7
-3
5
Type your answer in the box. Fractions like 3/4 are fine.
Hint
Substitute the x-value at the top of the empty column into the equation. Be careful with the negative.
Step-by-step solution
The empty column has x = -2. Substitute into y = 4x - 3:
y = 4(-2) - 3
Multiply first: 4(-2) = -8.
Then subtract: -8 - 3 = -11.
The missing value is -11.
Check: The table goes up by 4 every time x goes up by 1 (from -7 to -3 is +4). Going one step left from x = -1 should go down 4: -7 - 4 = -11 ✓
Tip: In a table for a line, equal steps in x give equal steps in y. Use that pattern to check every value you compute — it catches sign slips instantly.
Question 3 of 10 · Points in the coordinate plane
Hot spot
A point has a y-coordinate of 4, and its x-coordinate is the opposite of 2.
Click the point on the coordinate plane.
Click on the figure to mark your answer (or focus it and use the arrow keys).
Hint
First write the point as an ordered pair. What number is the opposite of 2?
Step-by-step solution
The opposite of a number has the same distance from 0 but the other sign. The opposite of 2 is -2.
So x = -2 and y = 4. The point is (-2, 4).
Plot it: from the origin, move 2 units left (because x is negative), then 4 units up (because y is positive).
The point is (-2, 4), in the upper-left region (Quadrant II).
Check: Read the clicked point back: it is 2 units left of the y-axis and 4 units above the x-axis, so x = -2, y = 4, and -2 is indeed the opposite of 2 ✓
Tip: Turn words into an ordered pair before you touch the graph. Write "( \_\_ ,\ \_\_ )" and fill in x first, then y.
Question 4 of 10 · Slope from a graph, equation or table
No calculatorDrag and drop
Drag each line to the box that describes its slope.
Positive slope
Negative slope
Zero slope
Undefined slope
Tap a tile, then tap a box to place it.
Hint
Think about the picture of each line. Rising, falling, flat, or straight up and down?
Step-by-step solution
y = 4x: m = 4 > 0, the line rises left to right → positive.
Line through (1, 5) and (3, 1): m = \frac{1 - 5}{3 - 1} = \frac{-4}{2} = -2 < 0 → negative.
y = 5: every point has y = 5, a flat (horizontal) line. Rise = 0, so m = \frac{0}{\text{run}} = 0 → zero.
x = -2: every point has x = -2, a vertical line. Run = 0, and division by zero is undefined → undefined.
Answer:y = 4x → positive; (1,5) & (3,1) → negative; y = 5 → zero; x = -2 → undefined.
Check: Two points on x = -2, e.g. (-2, 0) and (-2, 3): \frac{3 - 0}{-2 - (-2)} = \frac{3}{0} — undefined ✓
Tip: "Horizontal → Zero, Vertical → Undefined." Horizontal lines are y = \text{number}; vertical lines are x = \text{number}.
Question 5 of 10 · Slope from a graph, equation or table
Two points on the line below are marked. Use them to find the slope of the line.
Hint
Use the two marked points. Count how far up and how far right you go from one to the other.
Step-by-step solution
The marked points are (-4, -1) and (4, 5).
Rise (change in y): 5 - (-1) = 6.
Run (change in x): 4 - (-4) = 8.
Slope:
m = \frac{\text{rise}}{\text{run}} = \frac{6}{8} = \frac{3}{4}
The line rises from left to right, so a positive slope makes sense.
The slope is \tfrac{3}{4}.
Check: From (4, 5), go back 4 left and 3 down: (0, 2). The graph crosses the y-axis at 2 ✓
Tip: Use points where the line crosses grid intersections exactly (the marked points). Always reduce the fraction and check the sign against the picture: rising = positive.
Question 6 of 10 · Graph linear equations
Dana makes the same deposit into her savings account every week. The graph shows her balance.
What does the slope of the line represent?
Hint
Slope = change in balance ÷ change in weeks. Use the two marked points.
Step-by-step solution
The marked points are (0,\ 300) and (8,\ 900).
Change in balance: 900 - 300 = 600 dollars.
Change in time: 8 - 0 = 8 weeks.
Slope:
m = \frac{600}{8} = 75 \text{ dollars per week}
In this situation, the slope is how fast the balance grows: Dana deposits $75 each week.
Answer: she deposits $75 per week.
Check: Starting from $300, 8 deposits of $75 add 8 \times 75 = 600, giving $900 ✓
Tip: The units of the slope are (vertical units) per (horizontal unit) — here dollars per week. The $300 is the starting balance (the y-intercept), not the weekly deposit.
Question 7 of 10 · Key features of graphs and tables
No calculator
The graph of f is shown. Assume the graph keeps going in the same way beyond the grid.
As x increases without bound, what happens to f(x)?
Hint
Follow the right end of the curve. Is it heading up, heading down, or levelling off?
Step-by-step solution
"As x increases without bound" means: follow the graph far to the right.
Past the maximum at (-1, 9), the curve keeps falling. It crosses the x-axis at (2, 0) and keeps going down, faster and faster.
Nothing stops it: the right end points downward forever.
So f(x) decreases without bound (it goes toward -\infty).
Tip: A parabola that opens down has both ends pointing down; one that opens up has both ends pointing up. Crossing the x-axis does not mean the graph stops there.
Question 8 of 10 · Points in the coordinate plane
A parking lot is a rectangle. On a site plan measured in meters, its corners are at (-5,\ 3), (2,\ 3), (2,\ -1) and (-5,\ -1). A fence will go all the way around the lot.
How many meters of fence are needed?
Hint
Find the length of a horizontal side and of a vertical side. Then add all four sides.
Step-by-step solution
Horizontal side from (-5, 3) to (2, 3) (same y):
2 - (-5) = 2 + 5 = 7\text{ m}
Vertical side from (2, 3) to (2, -1) (same x):
3 - (-1) = 3 + 1 = 4\text{ m}
Perimeter = all four sides:
P = 2(7) + 2(4) = 14 + 8 = 22\text{ m}
The fence must be 22 meters long.
Check: Walk around the lot: 7 + 4 + 7 + 4 = 22 ✓ (Area would be 7 \times 4 = 28 square meters — a different question.)
Tip: Fence, border, trim = perimeter (add sides). Carpet, paint, sod = area (multiply). Subtracting a negative coordinate means adding its distance.
Question 9 of 10 · Unit rate as slope
Fill in
The graph compares the distance two cars can travel on a given amount of gasoline.
On 12 gallons of gasoline, how many more miles can Car A travel than Car B?
miles
Type your answer in the box. Fractions like 3/4 are fine.
Hint
Find each car's miles per gallon from its marked point. Then use 12 gallons for both.
Step-by-step solution
Car A: the point (4,\ 120) gives
\frac{120 \text{ mi}}{4 \text{ gal}} = 30 \text{ mi/gal}
Car B: the point (5,\ 110) gives
\frac{110 \text{ mi}}{5 \text{ gal}} = 22 \text{ mi/gal}
