4. The diagram below shows a doghouse that Calvino built.
1.5 ft
2.0 Ft
What is the volume of the doghouse?
A. 55.6875 ft
B. 15.1875 Ft
C. 40.5 ft
D. 60.75

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)

40 x 50 = 2000

step-by-step explanation:

the answer is 21%.
