Explanation of linear equations and four types of slopes: positive, negative, zero, and undefined. Practice problems for the students are provided and a reinforcement activity using a graphing calculator is offered for the teacher's use.

Practice finding the equation of a line passing through two points. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Print or create worksheets or flashcards to assess students' understanding of finding slope.

Watch how a graph is altered when key elements of the equation change. This lesson focuses on how to manipulate the equation of a line in slope intercept form to match the graphs provided deepening the understanding of both the slope and...

Given two points, the slope and a point, or the slope and the y-intercept, the student will write linear equations in two variables.

An introduction to the history of linear equations and how they relate to science.
