Pls answer B. C. and D.

B. Plug 2 in for “x” in “y=3x-2”. If you don’t get -1, the. You know that point is not a solution. In this case, we get 4, which is not equal to -1.

C. Again, you plug 2 in for “x”. Here the answer is in fact -1, so we know that (2,-1) is a solution.

D. You just graph the two lines. As we can see, (2,-1) only falls on one of the equations. This means that (2,-1) is only a solution of “y=-2x+3”.
