Charge Graphs (B) - Equations WORKSHEET

Enhance students' ability to interpret charge graphs with this worksheet, which connects real-life graphs to linear functions in the form y = mx + c. Learners will find the equations of straight lines and understand how the y-intercept and gradient represent a fixed charge and charge per unit in section A. This section leads pupils to match linear equations with charge scenarios and their corresponding graphs in section B. Finally, students will form equations themselves from scenarios such as, “A taxi company charges a fixed fee of £3.70 and 70 p per mile.” This approach helps reinforce their understanding of how linear functions apply to real-world situations.
