Answer: A. y+8=-2(x-4)
Step-by-step explanation: Point-slope form is y-y₁=m(x-x₁), in which you only substitute three values: the slope, and the x and y coordinate. So, since the slope is -2, you replace it with m. And, if the point is (4, -8), you would substitute the 4 in for x₁, but the -8 is a little more complicated because it is negative. Basically, the negative and the minus sign cancel out and it becomes a plus sign.
