Question

Write the equation of a line that is perpendicular to y = 5 and that passes through the point (-7,-5).

Answer 1

x = -7

Explanation:

The equation of the line in standard form is y=5.

This is a horizontal line, so the perpendicular line will be a vertical line of the form x=a.

Since we are given that the line should pass through the point (−7,−5) then the equation of the line is x=−7.
