Question

Perpendicular to y = -8. Contains (10,-20)

Answer 1

x = 10

Explanation:

y = - 8 is a horizontal line parallel to the x- axis

A line perpendicular to it will therefore be a vertical line parallel to the y- axis with equation

x = c ( c is the value of the x- coordinates the line passes through )

the line passes through (10, - 20 ) with x- coordinate 10 , then

x = 10 ← equation of perpendicular line
