You get a circle of radius #7# and centered in the origin.

Explanation:

You can think of it in polar coordinates (where you are given a radius from the origin and an angle with the positive #x# semi-axis).
In this case your equation tells you that you need to plot all points at distance #7# from the origin at any possible angle...i.e., a circle with center in the origin and radius #7#!
