A packing box has the dimensions 3 by 2 by 51 2
feet. What is the volume of the box?
A rectangular prism with a length of 3 feet, width of 2 feet, and height of 5 and one-half feet.
Use the formula V = Bh to calculate the volume of the packing box.
The area of the base of the box, B, is ft.2.
The volume of the box is ft.3.

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)
