2. Graphing Lines ­ 2
"Using the Intercepts Method"
There are 2 Intercepts for any linear equation:
• x-intercept: where line crosses the x­axis
• y-intercept: where line crosses the y­axis
*to find x-intercept from any eq'n, let y = 0, and solve for x.
*to find y-intercept from any eq'n, let x = 0, and solve for y.

6. Graphing Lines ­ 3
"Using Slope‐Intercept Form"
y = mx + b the slope­intercept form of a linear eq'n.
* To graph using this method,
we MUST convert equations to slope-intercept form
• Graph x ­ 2y = 2 using slope­int. method
