Is (2, -3) a solution of x%5E2%2B2y+=+-2?
To answer this question, you simply substitute the x- and y-coordinates from the given point (2, -3) into the equation and see if the left side is equal to the right side.
x%5E2%2B2y+=+-2 Substitute x = 2 and y = -3
%282%29%5E2%2B2%28-3%29+=+-2 Evaluate.
4-6+=+-2
-2+=+-2
The answer is yes and the the reason is that the x- and y-coordinate values of the given point satisfy (constitute a solution of) the equation.
