Using the equation, 5=-2(-1)+3 is in fact an equality, so it is a solution.
graph y=-2x+3, which has y-intercept +3 and slope -2. See if (-1, 5) is on the line. It is.

You can graph the line using the y-intercept and the slope given in the equation and estimate if the point is on the line; however it is better to solve it algebraiclly. The most accurate and efficient way to solve this problem is the plug in the x-value (-1) and the y-value (5) into the equation and see if the equation is a true statement.

You can conclude that (-1, 5) is a solution of that equation.
