Question

Which of the following lines are perpendicular to the line y = –x + 4? (you may choose more than one answer) (2 points) Responses 2x – y = 1 2 x – y = 1 y = 2x y = 2 x 2x + y = 1 2 x + y = 1 x – y = 2 Image with alt text: one-half x – y = 2 2x – y = 3

Answer 1

The lines that are perpendicular to y = -x + 4 are:
- 2x + y = 1
- y = 2x
- 2x + y = 1
- one-half x - y = 2
