9th Grade Slope and Linear Equations Worksheet — Level 1 — Practice Set 2 — Answers
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 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: −2
- slope = rise ÷ run = (11 − 5) ÷ (−2 − 1)
- = 6 ÷ −3 = −2
Answer: slope −6; y-intercept 5
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: −2
- slope = rise ÷ run = (14 − 6) ÷ (0 − 4)
- = 8 ÷ −4 = −2
Answer: 3
- slope = rise ÷ run = (4 − (−2)) ÷ (4 − 2)
- = 6 ÷ 2 = 3
Answer: −2
- slope = rise ÷ run = (−8 − 2) ÷ (10 − 5)
- = −10 ÷ 5 = −2
Answer: 3
- slope = rise ÷ run = (9 − (−3)) ÷ (0 − (−4))
- = 12 ÷ 4 = 3
Answer: slope −6; y-intercept 0
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 −2; y-intercept 0
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 −4; y-intercept −9
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.
