Checking to See If You've Actually Found the Real Solution to a System of Equations

Suppose you graph two equations in a system of equations to find out where they intersect--but suppose you're not sure if you drew the lines correctly, or maybe you can't quite tell where the exact intersection point is: Here's how to check your intersection point (solution) to know for sure if it's right or not!
