8. Could an angle be complementary to itself? If, so what would it’s measure be? 9. Could an angle be supplementary to itself? If so, what would its measure be?

8) angle that is complement of itself is 45°

9) When an angle is its own supplement, that means that the angle, plus itself, will equal 180 degrees.

Step-by-step explanation:

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)
