Which choice would most likely result in a negative association between the variables? A.
time spent exercising and the number of calories burned

B.
time spent doing homework and the number of problems left to complete

C.
miles driven and the gallons of gasoline used

D.
hours worked and the amount of money earned

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)
