5 x + 8 y = 9

15 x + 24 y = 27

For each real number

r

, which of the following points lies on the graph of each equation in the

x y

-plane for the given system?

(r, - \frac{5 r}{8} + \frac{9}{8})

(- \frac{5 r}{8} + \frac{9}{8}, r)

(- \frac{5 r}{8} + 9, \frac{5 r}{8} + 27)

(\frac{r}{3} + 9, - \frac{r}{3} + 27)
