Exploring Solutions to Systems of Equations by Graphing

The video tutorial explains how to solve systems of equations by graphing. It begins with converting equations into slope-intercept form, followed by graphing them on a coordinate plane. The intersection point of the lines is identified as the solution, which is then verified by substituting back into the original equations.

What is the first step in solving systems of equations by graphing?

• Graph each equation on the same coordinate plane

• Check the solution by substituting the values

• Find the intersection point of the lines

• Write the equations in slope-intercept form
