[Free Registration/Login may be required to access all resource tools.] Use slopes to determine if two lines are parallel.

In this instructional activity on slope, students explore how the rate of change can be identified using a graph, a set of points, and a table.

This Northeast Parallel Architectures Center of Syracuse University site contains a brief description of the point-slope form for equations along with the formula.

The handout has learners estimate the slope of a given line. The math graph is available in PDF format.

This lesson demonstrates how to find the rate of change in functions with linear relationships. It is 3 of 5 in the series titled "Finding Rates of Change in Linear Relationships."

In this practice quiz, students are asked to determine the slope of each line graph. Includes hints.
