Hello!
All points that are 12 units from (5, -3) form a circle, with center (5, -3) and radius 12. Recall that the formula for a circle with radius r and center (h, k) is:

So, in your case:

The points on the y-axis are the ones in which x = 0. So using that in our equation:

We get that:

Those are the two points on the y-axis that are 12 units away from (5, -3)

I hope this helps!
