<b>Example:  </b>Graph <img style="vertical-align: middle;" alt="" src="http://www.mathlocker.com/images/graphing_linear_1.bmp">

<table cellspacing="0" border="1" cellpadding="15" bordercolor="29527A"><tr><td width="200px">
This equation is already in slope-intercept form:  <img alt="" src="http://www.mathlocker.com/images/graphing_linear_2.bmp">.<br>
What luck!<br>
<img style="vertical-align: middle;" alt="" src="http://www.mathlocker.com/images/graphing_linear_3.bmp"> (slope)<br>
<img alt="" src="http://www.mathlocker.com/images/graphing_linear_4.bmp"> (y-intercept)
</td><td style="width: 200px">
Graph the y-intercept<br><br>

<table cellspacing="0" border="1" cellpadding="15" bordercolor="29527A"><tr><td style="width: 200px">Slope is <img alt="" src="http://www.mathlocker.com/images/graphing_linear_5.bmp"><br>
So go up 1 and right 2.<br><br>

</td><td style="width: 200px">
Connect the dots.<br><br>

</td></tr></table>
<br><p>You can use this method to graph any linear equation.  It's fast, it's easy, and it works every time!</p>
