12. brick is a square
4x -4
?
A
paver
with
sides of x feet in length. A
gardener is using the pavers for
the border of the custom
garden shown. The perimeter 3x
of the garden is 100 feet.
What is the length of the 4th side?
7x + 3

it could be a ..idk tho

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)
