What is the constant rate of change?
A 2
B 4
C 1/2
D -2

C- 1/2

Step-by-step explanation:

the graph shows a line that goes up 1 square, and to the right 2 squares. Put x over y and you get 1/2, your answer.

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)

43

step-by-step explanation:

not sure if this is supposed to be a trick question. 43 is the only one that makes any sense.
