Answer:
B
Explanation:
Choose an x point. Then plug it in and see if you get the correct y.
For example, I chose an x point of -1. When x = -1, you can see that y = 4.
Plug it in to the equations, and you find that B is correct.
y (4) =
(-1 x -1) - 2x ( 2 times -1) + 1
4 = 1 - (-2) + 1
4 = 1 + 2 + 1
4 = 4
