Which of the following pairs of points both lie on the line whose equation is 3xy= 2? 


(3,2) and (1,5) 

(2,4) and (3,7) 

(2,4) and (1,5) 

(2,2) and (1,5)


(3,7) and (3,2) 


Explanation of Answer: Test each pair: Only (2, 4) and (3, 7) satisfy the equation.
3(2)  4 = 6  4 = 2, and 3(3)  7 = 9  7 = 2.
None of the other pairs work.
