Question

Prompt

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?

2 x + 5 y = 3

8 x + 20 y = 12

(r, - \frac{5 r}{2} + \frac{3}{2})

(r, \frac{2 r}{5} + \frac{3}{5})

(\frac{r}{4} + 3, - \frac{r}{4} + 12)

(- \frac{5 r}{2} + \frac{3}{2}, r)
