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
X-Intercept Where Graph Crosses X-Axis
Y-Intercept Where Graph Crosses Y-Axis
3
Finding X and Y Intercepts
Use Zero to Find the X and Y Intercepts Make a
T-Chart Substitute Zero for X to find
Y Substitute Zero for Y to find X Graph the Line
2x 3y 6

Graphing Lines Using Intercepts
3x 4y 12
4x 2y -8
5
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
