A construction crew is extending a highway sound barrier that is 13 miles long. The crew builds 1/2 of a mile per week. Write an equation in slope-intercept form that represents the length y​ (in miles) of the barrier after x​ weeks.

$$N=\dfrac{W}{t}=\dfrac{\frac{1}{2}ml}{wk}\\ \color{blue}W=W_0 +N\cdot t$$

$$W\ [in\ miles]=13\ miles+\dfrac{\frac{1}{2}\ mile}{week}\cdot t\ [in\ week]$$

$$y\ [in\ miles]=13\ miles+\dfrac{\frac{1}{2}\ mile}{week}\cdot x\ [in\ week]$$
