Question

D. x= -1 and y = -1
Is it perpendicular, neither, of parallel. Show work

Answer 1

Perpendicular.

x = -1 is a vertical line intersecting the x-axis at (-1, 0).

y = -1 is a horizontal line intersecting the y-axis at (0, -1).

Because these lines are both straight, they will eventually intersect at (-1, -1). They will also form 90° angles, the definition of perpendicular.
