You can put this solution on YOUR website! Shortest distance to the y axis is what is helpful. No change in y value, from y=-3. You would form a triangle. One point is the given point (4, -3). Another point is (0, -3) which is the distance TO the y axis. The last point is ON the y axis but 6 units from (4, -3). You just need the Distance Formula.
In fact, you might try this with just Pythagorean Theorem, and then avoid formal use of Distance formula. You have two lengths. One is 6 units, the other is 3 units. Size of the other leg?
 , since the hypotenuse is 6 units.
 units long, but really,  or  .
Up 5 units from -3 is -3+5=2.
Down 5 units from -3 is -3-5=-8.
The answer for the point is then either or both of (0,2) or (0,-8).
