P heee 20 points to brainliest which ordered pairs are on the line 3x−4y=93x−4y=9 ? select each correct answer. (−1,3) (2/3,−7/4) (−5,−6) (1,−3/2)

The first thing you should do is verify that the ordered pairs satisfy equality. If so, then that pair ordered belongs to the line. Let us begin:
 3x-4y = 9

 (-1.3)
 3 (-1) -4 (3) = 9
 -3-12 = 9
 -15 = 9 (Does not belong)

 (2/3, -7 / 4)
 3 (2/3) -4 (-7/4) = 9
 6 + 28 = 9
 34 = 9 (Does not belong)

 (-5, -6)
 3 (-5) -4 (-6) = 9
 -15 + 24 = 9
 9 = 9 (Yes, it belongs)

 (1, -3 / 2)
 3 (1) -4 (-3/2) = 9
 3 + 6 = 9
 9 = 9 (Yes, it belongs)

 answer
 ordered pairs are
 (-5, -6)
 (1, -3 / 2)

The correct answer is 7
