10th Grade Slope and Linear Equations Worksheet — Level 2 — Practice Set 3 — Answers
Show your work. Slope = rise ÷ run; the equation of a line can be written as y = (slope)x + (y-intercept).
Answer: −
- slope = rise ÷ run = (0 − (−1)) ÷ (−10 − (−5))
- = 1 ÷ −5 = −
Answer:
- slope = rise ÷ run = (−1 − 5) ÷ (−10 − (−6))
- = −6 ÷ −4 =
Answer: y = −5x + 8
- y = −5x + (y-intercept)
- 18 = −5 × (−2) + (y-intercept)
- y-intercept = 18 − 10 = 8
- y = −5x + 8
Answer: y = −5x + 6
- y = −5x + (y-intercept)
- 21 = −5 × (−3) + (y-intercept)
- y-intercept = 21 − 15 = 6
- y = −5x + 6
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: −1
- slope = rise ÷ run = (4 − 0) ÷ (−5 − (−1))
- = 4 ÷ −4 = −1
Answer: slope 5; y-intercept 6
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 = (−2 − (−5)) ÷ (−10 − (−6))
- = 3 ÷ −4 = −
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: y = 5x + 2
- y = 5x + (y-intercept)
- 17 = 5 × 3 + (y-intercept)
- y-intercept = 17 − 15 = 2
- y = 5x + 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.
