Mrs. W buys 10 pounds of ground meat to make hamburgers. She plans to make one-third pound burgers for a party. How many burgers will mrs. w be able to make?

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)

1. perpendicular

2. parallel

3. perpendicular

- (2, -7)

- lines r and s and lines t and u must be parallel
