After this lesson, you will be able to graph linear equations in slope-intercept form.

The lesson begins by teaching you how to write a linear equation in slope-intercept form. It leads you to learn how to identify the slope and the y-intercept from the equation. It concludes with showing you how to graph the equation by using the slope and y-intercept.

Learn about slope of the line by seeing how Furious Films plan and shoot for their next blockbuster movie.

This video includes key concepts, notation, and vocabulary such as slope (the ratio of the change in vertical movement, or the change in x over the change in y); y-intercept (the value of y when the value of x is equal to zero); and slope-intercept form (y=mx+b, where m is the slope and b is the y-intercept).

Before watching this video, you should already be familiar with linear equations, properties of equality, and solving equations by isolating a variable.

After watching this video, you will be prepared to solve real world problems that involve constant rates, which can be considered as the slope of a line when the problem is represented by an equation.
