Write two equations that are the same line.

Work Step by Step

In order to solve a system of equations by graphing, first graph each of the given equations. Next, look for intersections between the equations, which are solutions to the equations. If the equations are the same line, then there are infinite solutions. Thus, write an equation, and then write a different version of the equation that is actually just the same line to do this.
