Which of the following doesnot represent pair of integers (a, b) such that a÷b=3

-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
