Finding an Endpoint with a Midpoint

The video tutorial explains how to find an endpoint when given a midpoint and another endpoint. It introduces the concept, explains the midpoint formula, and provides a step-by-step guide to calculate the missing endpoint by analyzing changes in coordinates. The tutorial concludes with a summary of the process.

How do you find the other endpoint if the known endpoint is negative four and the midpoint is negative nine?
