Show your work. Slope = rise ÷ run; the equation of a line can be written as y = (slope)x + (y-intercept).
- AYes
- BNo
Answer: Yes
Substitute x = 0: y = −5 × 0 + 8 = 8, which matches.
Answer: slope 2; 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.
- AYes
- BNo
Answer: No
Substitute x = −5: y = −5 × (−5) − 3 = 22, not 19.
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.
- AYes
- BNo
Answer: No
Substitute x = −5: y = 1 × (−5) − 1 = −6, not −8.
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.
- AYes
- BNo
Answer: No
Substitute x = −5: y = −3 × (−5) − 8 = 7, not 9.
- AYes
- BNo
Answer: No
Substitute x = −4: y = −4 × (−4) + 2 = 18, not 17.
- AYes
- BNo
Answer: No
Substitute x = 0: y = 2 × 0 − 4 = −4, not −1.
- AYes
- BNo
Answer: No
Substitute x = 1: y = −5 × 1 + 3 = −2, not 1.
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.
