Answer: -9,3 and -15,-1 don’t
Explanation
a divided by b = 3
it’s (a,b) so a is out x value and b is the y value, so it’s x divided by y
(-9, 3) ❌
In this case our x is -9 and y is 3
-9 divided by 3 = -3
If the 3 was negative, this would work
(15,-1) ❌
Now our x is -15 and our y is -1
-15 divided by -1 = 15
If it was -3 instead of -1 this would work
(6,2) ✔️
Now x is 6 and y is 2
6 divided by 2 = 3
So this works
(-3, -1) ✔️
Now x is -3 and y is -1
-3 divided by -1 = 3
So this also works
