10) Which of the following pairs of points both lie on the line whose equation is 3x-y= 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

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.
