Question

Prompt

3 x + 5 y = 8

9 x + 15 y = 24

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}{3} + \frac{8}{3})

(r, \frac{3 r}{5} + \frac{8}{5})

(- \frac{5 r}{3} + \frac{8}{3}, r)

(\frac{r}{3} + 8, - \frac{r}{3} + 24)
