Show your work. Slope = rise ÷ run; the equation of a line can be written as y = (slope)x + (y-intercept).
Answer: slope −2; 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 = (0 − 6) ÷ (5 − 2)
- = −6 ÷ 3 = −2
Answer: slope 6; y-intercept 1
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 −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 −3; 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: slope 1; 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: slope 5; 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 −6; 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.
Answer: 2
- slope = rise ÷ run = (10 − 6) ÷ (8 − 6)
- = 4 ÷ 2 = 2
Answer: −3
- slope = rise ÷ run = (−13 − (−4)) ÷ (7 − 4)
- = −9 ÷ 3 = −3
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:
