9th Grade Slope and Linear Equations Worksheet — Level 2 — Answers
Show your work. Slope = rise ÷ run; the equation of a line can be written as y = (slope)x + (y-intercept).
Answer: slope −6; 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:
- slope = rise ÷ run = (0 − 1) ÷ (−2 − 2)
- = −1 ÷ −4 =
Answer: y = 5x + 4
- y = 5x + (y-intercept)
- −11 = 5 × (−3) + (y-intercept)
- y-intercept = −11 − (−15) = 4
- y = 5x + 4
Answer: y = −3x + 1
- y = −3x + (y-intercept)
- 1 = −3 × 0 + (y-intercept)
- y-intercept = 1 − 0 = 1
- y = −3x + 1
Answer: y = −5x − 5
- y = −5x + (y-intercept)
- −5 = −5 × 0 + (y-intercept)
- y-intercept = −5 − 0 = −5
- y = −5x − 5
Answer: slope −5; y-intercept 2
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: 1
- slope = rise ÷ run = (4 − 6) ÷ (−4 − (−2))
- = −2 ÷ −2 = 1
Answer: 2
- slope = rise ÷ run = (−1 − 5) ÷ (2 − 5)
- = −6 ÷ −3 = 2
Answer:
- slope = rise ÷ run = (0 − 4) ÷ (−4 − (−1))
- = −4 ÷ −3 =
Answer: slope −5; 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.
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.
