For Items 3–5, use the figure shown.

Find the slope of each line in the figure.

Five lines graphed on the same coordinate plane. Line m passes through the points negative 15.5 comma 0 and 0 comma 6.2. Line n passes through the points negative 5 comma negative 6.8 and 12 comma 0. Line p passes through the points negative 4 comma 8 and 4 comma negative 12. Line q passes through the points 6.8 comma 13 and 12 comma 0. Line r passes through the points 6.8 comma 13 and 0.4 comma negative 3.
