This clip explains how the slope equation is mapped on a coordinate plane and how the different variables, such as x, influence the mapping of the line. It also explains the slope-intercept form of the equation, y = mx + b.

This clip explains linear equations and how the equation influences the slope of a line on a graph.

High school teacher Mr. Jaime Escalante teaches his students about negative and positive numbers. He uses a real-world example of digging into sand at the beach to help students understand the concept.

Teacher Dawn teachers her students about linear equations. She graphs the relationship between incentive and productivity on a coordinate plane with the equation y = 1.5x. She jokes that they can ask for a greater incentive to make a higher allowance.
