Select all the graphs that represent a proportional relationship between x and y. A) 4 4 00+ 4 4 4 8 8-4 -4 -8+ B ) D) у y 6 8 4 12 X 4 -4+ 4 -8+

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

the first one, all those points on the line just make a strait line.

exactly you go it
