The area of the rectangle portion is base times hight, in this case 6 * 10, which we get 60 for. Next to find the area of the triangle we calculate 1/2 base times hight, or 1/2 6 * 7, which we get 21 for. 60 + 21 = 81m^2
start with y= m(x+9)
Use the distributive property:
y= mx+9m
Now you want x to decrease by 6:
so y ' = m(x-6) + 9m
Use distributive property again:
y'= mx - 6m + 9m
y' = (mx+9m) - 6m
y' = y - 6m
So the value of y decreases by 6m.
