## Elementary and Intermediate Algebra: Concepts & Applications (6th Edition)

A point is a solution of an equation if its x and y-coordinates satisfy the equation. Substitute the x and y values of the point into the equation to obtain: $y=5-x \\-3=5-(-2) \\-3=5+2 \\-3=7$ Thus, the given point is NOT a solution of the given equation.
