Can someone please help me answer these two questions? I have already answered one, and need it checked.
Give any three ordered pairs that are solutions of the equation:
1. xy=6
(12,6)
(10,4)
(15,9)
2.3x  2y = 0
???
3.2x 3y = 12
I have only one ordered pair for this:
(9,2)
2 more needed
Thanks!

It would be easier if you solve the equations for y, then plug in a value for x.
3x  2y = 0
add 3x to both sides
2y = 3x
divide both sides by 2
y = (3/2) x
Now just pick numbers for x (because of the 2 in the denominator, it will help to pick even integers).
x = 2
y = (3/2) 2
y = 3
so (2, 3)
x = 0
y = (3/2) 0
y = 0
so (0, 0)
x = 2
y = (3/2)(2)
y = 3
so (2, 3)

Thank you Rick!!
I need two more for the third one though...
