When solving linear systems by graphing we need to do the following:
Steps to Solve
1. Express the equations in slopeintercept form (y = mx + b).2. Graph each line on the same axes.3. Find the point of intersection. This is the solution.
Using a Graphing Calculator
1. Express in slopeintercept form.2. Enter them into the equation editor (y=) then press Graph.3. Find the point of intersection:
