Understanding Slope-Intercept Form

The video tutorial explains how to graph a linear equation using the slope-intercept form, Y = MX + B. It covers rearranging the equation to solve for Y, identifying the slope and y-intercept, and using these to plot the graph. The tutorial provides a step-by-step guide to subtracting terms, multiplying by the reciprocal, and plotting points using the rise over run method. The video concludes with a review of the process.

What is the general form of a linear equation in slope-intercept form?

• Y = BX + M

• X = MY + B

How is the slope of a line often expressed?

• As the change in x over the change in y

• As the rise over the run

• As the run over the rise

• As the y-intercept over the x-intercept
