Lesson Summary:

This lesson introduces the slope-intercept form of a line and how to identify the slope and y-intercept from an equation. The instructor provides two equations to graph and then demonstrates how to find the slope and y-intercept by looking at the graph. The lesson also covers identifying the slope and y-intercept from different equations and introduces the slope-intercept form of a line, y=mx+b. By the end of the lesson, students will have a solid understanding of how to identify and graph lines using the slope-intercept form of a line.

Lesson Description:

This is an introduction to the slope-intercept form of a line, and how to identify the slope and y-intercept from an equation. This is part 14 of a series of videos about graphing lines.

    This lesson is an introduction to graphing lines from equations that are in slope-intercept form. The slope and y-intercept are found from these equations as well. This is a very basic introduction to a very important form of a line.
