Lesson Summary:

In this lesson, you will learn how to solve an equation for y, which is essential for graphing lines. By isolating the term with y and rearranging the equation into slope-intercept form (y = mx + b), you can easily plug in values for x to create a table of ordered pairs and graph the line. The transcript includes examples and practice problems to solidify your understanding of this important concept.

Lesson Description:

Covers how to solve an equation for y so it is easy to plug in convenient values for x, make a table of ordered pairs, plot the points and graph the line. Also, solving for y will be useful to get equations in slope intercept form and graph using that method, which is covered in later videos. This is part 5 of a series of videos about graphing lines.

    This lesson explains the process of changing an equation from standard form into slope-intercept form by solving the equation for y. These equations are then used to make a table of values and graph the equation. This process is explained very well and several example problems are shown in the video.
