Yes!
If you substitute the point for the corresponding x and y values, you get -1+3 which does indeed equal 2.

If you move x to the other side by subtracting like this:
x-x+y=2-x
y=2-x
Then you plug in those points
3= 2- (-1)
do the math... and the answer is yes.
The ordered pair (-1, 3) is a solution to x+y=2
x-x+y=2-x
y=2-x

3= 2- (-1)
