This video tutorial explains how to graph linear equations using the slope-intercept form. It begins with an overview of graphing as a representation of solutions to equations, emphasizing the relationship between inputs and outputs. The tutorial then introduces the slope-intercept form, y = mx + b, explaining the roles of slope (m) and y-intercept (b). It provides step-by-step instructions for graphing, including plotting the y-intercept and using the slope to find additional points. The video concludes with examples to illustrate the process.

What does a graph represent in the context of equations?

• A picture of all the solutions to an equation

• A visual representation of the equation's highest value
