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).

1.For the line y = 5x + 8, write the slope and the 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.

2.Find the slope of the line through (1, 5) and (−2, 11).

Answer: −2

  1. slope = rise ÷ run = (11 − 5) ÷ (−2 − 1)
  2. = 6 ÷ −3 = −2
3.For the line y = −6x + 5, write the slope and the y-intercept.

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.

4.Find the slope of the line through (4, 6) and (0, 14).

Answer: −2

  1. slope = rise ÷ run = (14 − 6) ÷ (0 − 4)
  2. = 8 ÷ −4 = −2
5.Find the slope of the line through (2, −2) and (4, 4).

Answer: 3

  1. slope = rise ÷ run = (4 − (−2)) ÷ (4 − 2)
  2. = 6 ÷ 2 = 3
6.Find the slope of the line through (5, 2) and (10, −8).

Answer: −2

  1. slope = rise ÷ run = (−8 − 2) ÷ (10 − 5)
  2. = −10 ÷ 5 = −2
7.Find the slope of the line through (−4, −3) and (0, 9).

Answer: 3

  1. slope = rise ÷ run = (9 − (−3)) ÷ (0 − (−4))
  2. = 12 ÷ 4 = 3
8.For the line y = −6x, write the slope and the y-intercept.

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.

9.For the line y = −2x, write the slope and the y-intercept.

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.

10.For the line y = −4x − 9, write the slope and the y-intercept.

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.
