Middle schoolers describe plotting functions on the Cartesian coordinate plane. They solve functions on paper and using an online tool to plot points on a Cartesian coordinate plane creating lines and parabolas.

Students investigate linear functions. In this mathematics lesson, students plot points onto a graph by solving the equations y=x and y=mx+b by being given numbers for x and solving for y.

Use this graphing linear functions worksheet to have learners graph three linear equations. They use a table of values, the intercept method, and slope-intercept form to graph three functions.

In this linear functions learning exercise, students graph 3 linear functions. Students graph each function by making a table of values given a linear function in standard form.

In this direct variation worksheet, students answer 4 multiple choice questions that involve identifying a direct and constant variation and writing the direct variation equation.
