Using the number line below, determine which of the following expressions are equal to −9. Select all that apply. A.
−12−(−3)
B.
−10−1
C.
−5−4
D.
−1−(−10)
E.
1−(−8)
F.
5−14

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)

i think it is 18
