Find points on the y-axis which are at a distance of 10 units from the point (8, 8).

We know that, x-coordinate of any point on y-axis = 0. Let point on y-axis which is at a distance of 10 units from (8, 8) be P(0, y). By distance formula, On squaring both sides, ∴ P = (0, y) = (0, 2) or (0, 14). Hence, points on the y-axis which are at a distance of 10 units from the point (8, 8) are (0, 2) or (0, 14).
