Linear Equation

A linear equation is a mathematical expression that describes a straight-line relationship between two quantities. In the context of cost equations, it models the total cost as the sum of a fixed fee and a variable fee that changes linearly with the number of miles driven.

Slope

The slope in a cost equation represents the rate of change in cost with respect to the number of miles driven. It indicates how much the cost increases per each additional mile. In the case of renting a truck, it represents the per-mile rental charge and shows the additional cost incurred for each mile added.

Graph Transformation

Changing the per-mile charge in the cost equation effectively changes the slope of the graph. For example, reducing the per-mile charge from a higher rate to $0.75 results in a less steep line, indicating that the cost increases more slowly with distance. This change reflects how adjustments in variable costs alter the overall cost progression in a linear model.
