Question

A potter is creating a design for a red-colored urn. He starts with the design shown on the coordinate grid.

Answer 1

Given:

the design is to be rotated about the line x = 1 to produce the shape of the urn. 

To generate a design for the urn, we need to draw a vertical line at x = 1, this will be our axis of rotation (or the basis for our mirror). We will use the mirror principle in making our design. So we will either draw half the shape of the urn at the left or right side of the axis of rotation.
