Graphing Linear Equations

A four-lesson unit on straight-line relationships: measure constant change, read slope-intercept form, graph the solution set, and translate between useful line forms.

Unit throughline

A linear equation is one relationship viewed through several coordinated representations.

This page organizes the unit. The actual teaching lives in the lessons below, so each lesson can keep one primary question and one primary learning object.

rate of change → y = mx + b → graph the line → translate forms
