In the figure, ABCD is a parallelogram. If the
areas of APDC and AAPD are 48 cm2 and
30 cm2 respectively, then the area of APBC is
A. 15 cm2
B. 18 cm2
C. 24 cm2
D. 36 cm2

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)
