How Do You Solve a System of Equations by Graphing?

Two equations. What's the solution to this system? How can you solve it? Can you write the two equations in slope-intercept form? Yes, you can. Now graph each equation. Look, the lines intersect. What does that mean? That means that there is a solution and the solution is the point where the lines intersect. Now plug that ordered pair into your original equations and check to see if it works.
