Exploring Slope-Intercept Word Problems

This lesson explains how to convert word problems into slope intercept form. It uses two examples: a cell phone bill with a flat fee and a per-text charge, and a car usage cost with a monthly fee and a per-mile charge. The lesson demonstrates how to rearrange terms to fit the y = mx + b format, identifying the slope and intercept in each scenario.
