Question

Write the equation of a line that is perpendicular to y=−1 and that passes through the point (8,-4)

Answer 1

Explanation:

y = -1 is the equation of a horizontal line, so a line perpendicular to that is a vertical line. It must have the form

x = constant

If it passes through (8,-4), then x = 8.

Final equation of the line:

x = 8
