Lesson Summary:

In this lesson, we learn the x and y intercept method of graphing lines, as well as the T chart method. The x and y intercept method works for most lines, but not if it goes to the origin or if it's a vertical or horizontal line. The T chart method is easier to use when the equation is solved for y. The key takeaway is to choose the method that is easiest for the particular equation, and that may involve using a combination of the two methods.

Lesson Description:

Shows more examples of how to graph lines by making a table or chart of ordered pairs, or using the x and y intercept method. It also shows how to decide which method is easiest for a given equation. This is part 8 of a series of videos about graphing lines.
