Identify an equation in point-alope form for the line perpendicular to y=-2x+8 that passes through (-3,9)

Step-by-step explanation:

Given line is y =-2x+8

By comparing the given line with the slope intercept equation y=mx+b we get that the slope of the given line is m =  -2

The concept is slope of a perpendicular line is -1/m

so slope of line perpendicular to the given line must be =-1/-2 = 1/2

so now we need a line with slope 1/2 and that passes throuh (-3,9)

Point slope equation is

y-9 =1/2(x-(-3))

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

answer is  

a.

p = 78
