Question

write an equation for the line perpendicular to the line ( y = 15 ) and passing through ( (7, -8) ). if possible, write a formula for a linear function whose graph is the given line. the equation of the line perpendicular to the line ( y = 15 ) and passing through ( (7, -8) ) is ( square ). (simplify your answer. type an equation.)

Explanation:

Step1: Identify given line type

The line $y=15$ is a horizontal line.

Step2: Find perpendicular line type

A line perpendicular to a horizontal line is vertical, with the form $x = a$, where $a$ is a constant.

Step3: Match x-coordinate of point

The line passes through $(7, -8)$, so $a=7$.

Answer:

$x=7$
