Answer:

While the coordinates would be a solution to the first equation, they are not for the second equation, so the answer to your question is no.

Explanation:

All you have to do is substitute the coordinates into the x and y values.

(2)-2(-1) = 2+2 = 4 We can tell that the coordinates worked for the first equation. Lets see if it works for the second, as well.

3(2) + (-1) = 6-1 = 5 Unfortunately, the coordinates were incorrect for the second equation.
