Lesson Summary:
In this lesson, you will learn how to quickly graph linear equations using intercepts. The intercepts are the points at which the line intersects the x and y axes, and exploiting the number zero makes the math easier. By finding the intercepts, you can draw a straight line on the coordinate plane, and it only takes two points to do so. With this shortcut, you can save time and eliminate the need for fractions in your equations.
Lesson Description:

Staff Review
A great explanation of the easy way to graph standard form equations using intercepts. If trying to graph equations in the form ax + by = c, this is a must-see! -

The description on how to do these types of problems was really good - drop the extra, corny narration and music. It takes up too much time and offers nothing to the student.
