Rotating points around a center point

Hello. I am currently writing a plugin for a custom program written by my professor. I have an image of a participant and I have a plugin already that allows me to pin point two points on their face. I can rotate the image and I want the points to rotate with the image. This is what I have:

    function varargout = rotateClockwise(plusMinus);

I'm not getting any errors, but the dots are not in the right place. I cannot figure out how to get the dots to rotate correctly--they are too low.
