Standard Form
Ax + By = C
A, B, and C are Numbers
2x + 3y = 6
Standard Form allows you to find the x and y intercepts quickly
X­Intercept: Where Graph Crosses X­Axis

Graphing Horizontal and Vertical Lines
Horizontal Lines have Slopes = 0
X does not Matter
Y always equals some number
Vertical Lines have Undefined Slopes
Y does not Matter
X always equals some number
x = 3
y = 2
