It involves describing a real-life situation where there is a constant rate of change. It requires identifying variables, setting up a linear equation in the form \( y = mx + b \) (where \( m \) is the slope and \( b \) is the `y`-intercept), and then solving for unknowns. These problems can include scenarios like calculating total cost given a fixed fee and a variable charge per unit, or predicting distance over time at a constant speed.
