I am using a program online called Hawkes Learning and that's the problem they gave me (I double checked that I typed it right) And they said the answer would be (0,0) (6, -4) But im not sure how they got that or why

well, we both understand the (0,0) part....

for the (6,-4), I guess they just want you to guess an ordered pair that fits into the equation 6x+9y=0

also, you notice that 6*6=36, 4*9 also =36.

so in other words you are just trying to find two numbers, one number multiply 6=-(the other number multiply 9)

So another solution can also be (9, -6)
