If you start at -40 you need 40 to get to 0 then add 40 to get there so B probly or C D
Because the side has to be increased by 50%
you find half of 8, which is 4 and you add 8+4 because you add the increased amount
8+4=12
you then just find the area.... so 12x12= 144
I don't see a list of options, but I know that the answer is y = -4x + 6.
Point - Slope Form: y - y₁ = m(x - x₁)
y - 2 = -4(x - 1)
y - 2 = -4x + 4
+ 2 + 2
--------------------
y = -4x + 6
First question: 0
