It takes caroline 22 minutes to ride her bike from sterling to potomac falls. it takes her 14 minutes to ride from potomac falls to fairfax. how many minutes will it take her to ride from sterling to fairfax if she goes through potomac falls?

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)

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
