Which best defines a function? a- a function is a special type of relation for which there is a rule that pairs each input with exactly one output. b-a function is a relationship that defines the connection between two variables. c-a function is a set of ordered pairs in which no y-value repeats. d-a function pairs input and output values with no particular pattern.

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)
