Explanation:

First, find the co-terminal angle for 1050^@1050∘. Note that if you start from the positive x-axis and go counterclockwise (standard position) then you will go around the circle twice and then terminate at 330^@330∘ which is the co-terminal for 1050^@1050∘.

Since r is negative (-7/2)(−72) it means that we have to plot the point on the opposite ray from 330^@330∘ which is the ray 150^@150∘.

So halfway between circle number 3 and 4 plot the point on the ray 150^@150∘.
