Lesson Summary:

In this lesson, part 2 of graphing lines using the slope-intercept method, the steps are outlined. The first step is to solve the equation for y, then identify the slope and the y-intercept. Next, plot the y-intercept, use the slope to find more points, and check a point on the graph to make sure it works in the original equation. The lesson includes examples of how to graph different equations using the slope-intercept method and explains how to handle equations that can't be put into slope-intercept form.

Lesson Description:

This is a part 2 of Graphing Lines using the slope intercept method. See Graphing Lines Part 15 for Part 1. This is part 16 of a series of videos about graphing lines.

    This lesson goes through many examples of changing an equation from standard form to slope-intercept form and graphing the lines. Horizontal and vertical lines are shown in this lesson also. If you like always using slope-intercept form to graph equations, this is a great lesson to watch to transform almost any equation into slope-intercept form.
