At John Dean High School, 42 seniors are enrolled in the
photography class and 35 seniors are enrolled in the sculpture class. Of these seniors, 15 are enrolled in both classes. How many of the 110 seniors enrolled at John Dean High School are NOT enrolled in either the photography class or the sculpture class?
A.18
B.33
C.48
D.77
E.92

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)
