Question

Find the locus of a point P that moves at a constant distant of three units from the y-axis

Answer 1

Three units from y-axis:

Let (h, k) be any point on the required path.

From the given data,

We have h = 3.

The locus of P(h, k) is obtained by replacing h by x and k by y.

∴ The required locus is x = 3
