The Ortiz family will travel from Indianapolis to Denver and back this summer. The driving distance between the two cities is 2,046 miles. They need to find out about how much the gas will cost for the entire trip. Their car travels about 24 miles using 1 gallon of gas. They usually spend about $3.24 per gallon of gas. Determine how many miles they will travel from Indianapolis to Denver and back.

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)
