Which statements accurately describe how to determine the y-intercept and the slope from the graph below?

C.

Step-by-step explanation:

You would start at the origin and move vertically (up and down) to find the y-intercept

The correct formula to find slope is

y2 - y1

x2 - x1

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
