1. The problem asks us to write an equation for Fawzia's salary $S$ after $n$ years at the company based on the graph. 2. From the graph, we see the salary increases linearly starting at $55000$ when $n=0$ and increases by $2000$ each year. 3. The general form of a linear function is $$S = S_0 + rn$$ where $S_0$ is the starting salary (y-intercept) and $r$ is the raise per year. 4. Here, $S_0 = 55000$ and $r = 2000$, so the equation is: $$S = 55000 + 2000n$$ 5. The y-intercept $55000$ represents Fawzia's starting salary before any raises (at $n=0$ years). 6. The slope $2000$ represents the annual raise amount added to the salary each year. Final answer: $$S = 55000 + 2000n$$
