Identify an equation in point-slope form for the line perpendicular to y=-2x + 8 that passes through (-3,9).
O A. y - 9 =-2(x+3)
O B. y+3 (x-9)
O C. y-9 - (x+3)
O D. y + 9 = 2(x-3)

Step-by-step explanation:

Given

Function;

Required

Find an equation perpendicular to the given function if it passes through (-3,9)

First, we need to determine the slope of:  

The slope intercept of an equation is in form;

Where m represent the slope

Comparing   to ;

We'll have that

Going from there; we need to calculate the slope of the parallel line

The condition for parallel line is;

Substitute

Divide both sides by -2

The point slope form of a line is;

Where and

becomes

Open the inner bracket

Hence, the point slope form of the perpendicular line is:

r and t.

both are 64 degrees.
