Question

Write the slope-intercept equation of the function f whose graph satisfies the given conditions.

The graph of f passes through (-9,-8) and is perpendicular to the line whose equation is x = 8.
The equation of the function is

Answer 1

Explanation:

y = 8, the one above is correct, we both are.

Answer 2

y = -8

Explanation:

line x = 8 is a vertical line so the line perpendicular has slope of 0

Using m = 0, x = -9, y = -8

y = mx + b

-8 = 0(-9) + b

b = -8

so y = -8
