Question

Find the equation of a line that is perpendicular to the line x=-4 and contains the point (-9,9)

Answer 1

9514 1404 393

Answer:

y = 9

Explanation:

The given line is a vertical line. The perpendicular line will be a horizontal line with the equation ...

y = constant

To make the line go through a point with a y-coordinate of 9, the constant must be 9.

y = 9 . . . . perpendicular to x = -4
