Exploring Systems of Equations through Graphing

What is the first step in graphing a system of equations?

• Check if the equations are in standard form

• Check if the equations are in slope-intercept form

• Plot the y-intercept

• Find the x-intercept

How do you convert a standard form equation to slope-intercept form?
