Lesson 9  (PH Text 5.5):  Standard Form     Ax + By = C
Objective:  to graph linear equations using intercepts to write and linear equations in standard form  x­intercept – the y­coordinate of a point where the graph crosses the x­axis y­intercept – the y­coordinate of a point where the graph crosses the y­axis
A, B, and C must be integers
A and B cannot equal zero
