Distributive property, I’ll mark brainliest if correct !!

1.   20 - 2 x

3.  -7 x - 21

5.   5 - 15 x

7.    20 x - 50

9.   1 - 4 x

11.   18 x - 8

13.   24 x + 36

Step-by-step explanation:

is there any photos or whatever?

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)
