1.) 21 and 28 are alternate exterior angles.
2.) 24 and 26 are same side interior angles.
3.) 25 and 27 are vertical angles.
4.) 22 and 28 are corresponding angles.
5.) 23 and 26 are alternate interior angles.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
