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

Writing an Equation in Standard Form:
1st: Start with Point Slope form:
2nd: Re-arrange so that x and y are on the same side of the =
3rd: Get rid of your fractions (if there are any)
