Show your work. Slope = rise ÷ run; the equation of a line can be written as y = (slope)x + (y-intercept).
Answer: slope −5; 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 = −5x − 8
- y = −5x + (y-intercept)
- −8 = −5 × 0 + (y-intercept)
- y-intercept = −8 − 0 = −8
- y = −5x − 8
Answer:
- slope = rise ÷ run = (−1 − (−6)) ÷ (6 − 4)
- = 5 ÷ 2 =
Answer: y = 5x − 7
- y = 5x + (y-intercept)
- −7 = 5 × 0 + (y-intercept)
- y-intercept = −7 − 0 = −7
- y = 5x − 7
Answer: y = −3x + 9
- y = −3x + (y-intercept)
- 3 = −3 × 2 + (y-intercept)
- y-intercept = 3 − (−6) = 9
- y = −3x + 9
Answer: slope −1; y-intercept −8
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:
- slope = rise ÷ run = (0 − (−1)) ÷ (2 − (−2))
- = 1 ÷ 4 =
Answer: slope −4; 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 = 2x + 9
- y = 2x + (y-intercept)
- 1 = 2 × (−4) + (y-intercept)
- y-intercept = 1 − (−8) = 9
- y = 2x + 9
Answer: −2
- slope = rise ÷ run = (9 − 1) ÷ (0 − 4)
- = 8 ÷ −4 = −2
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:
