Decompose the rectangle along the diagonal and recompose the two pieces to make a different shape. how does the area of this new shape compare to the area of the original rectangle? explain how you know

step-by-step explanation:

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
