Question

Which of the following equations represent a line that has a slope of –5 and that passes through (2, –6)? Check all of the boxes that apply.

y + 6 = –5(x – 2)

y – 2 = –5(x + 6)

y = –5x + 4

y = –5x – 28

Answer 1

The first and third equations.

- y + 6 = –5(x – 2) → y = –5x + 4, and y(2) = –5(2)+4 = –6.
- y = –5x + 4 → y(2) = –5(2)+4 = –6.

The second and fourth both simplify to y = –5x – 28, which gives y(2) = –38, not –6.
