Show your work. Slope = rise ÷ run; the equation of a line can be written as y = (slope)x + (y-intercept).
Answer: slope −3; y-intercept 4
In y = (slope)x + (y-intercept), the number multiplying x is the slope and the constant is where the line crosses the y-axis.
Answer: y = 3x + 9
- y = 3x + (y-intercept)
- 9 = 3 × 0 + (y-intercept)
- y-intercept = 9 − 0 = 9
- y = 3x + 9
Answer: y = x + 2
- y = 1x + (y-intercept)
- 6 = 1 × 4 + (y-intercept)
- y-intercept = 6 − 4 = 2
- y = x + 2
Answer: slope −2; y-intercept −1
In y = (slope)x + (y-intercept), the number multiplying x is the slope and the constant is where the line crosses the y-axis.
Answer: y = −x + 6
- y = −1x + (y-intercept)
- 3 = −1 × 3 + (y-intercept)
- y-intercept = 3 − (−3) = 6
- y = −x + 6
Answer:
- slope = rise ÷ run = (−5 − (−2)) ÷ (−3 − 2)
- = −3 ÷ −5 =
Answer: slope 2; y-intercept −7
In y = (slope)x + (y-intercept), the number multiplying x is the slope and the constant is where the line crosses the y-axis.
Answer: y = −4x
- y = −4x + (y-intercept)
- 12 = −4 × (−3) + (y-intercept)
- y-intercept = 12 − 12 = 0
- y = −4x
Answer: slope 4; y-intercept 3
In y = (slope)x + (y-intercept), the number multiplying x is the slope and the constant is where the line crosses the y-axis.
Answer: −3
- slope = rise ÷ run = (6 − (−3)) ÷ (−5 − (−2))
- = 9 ÷ −3 = −3
Marking tips
- Give credit for correct method even when the final answer slips — the working shows where the thinking went right.
- For open-ended tasks, use the success criteria as a checklist rather than looking for one "right" answer.
- Celebrate what went well first, then pick one thing to work on next.
Great work. Here's what to try next:
