Consider a small café that sells coffee at a fixed price. The café charges $3 for each cup of coffee sold. The graph of the linear equation \( y = 3x \) can model the total revenue (y) generated from selling x cups of coffee. This means if the café sells 0 cups of coffee, the revenue is $0, and for every additional cup sold, the revenue increases by $3. Therefore, if the café sold 10 cups, the total revenue would be $30, as represented by the point (10, 30) on the graph. This model illustrates how sales volume directly impacts the café's income in a linear fashion.
