Some of the most difficult GMAT Geometry questions are set on the coordinate plane. These problems ask you to think intuitively, at a high level, about issues such as slope and the way figures relate to one another.

It's no surprise that many test-takers find these questions difficult--most GMAT students don't spend enough time mastering the basics. If you haven't internalized how to calculate slope, or what it means for one line to have a slope of +3, you don't have a chance on questions where those details are just one aspect of a larger whole.

Start strengthening your coordinate geometry skills with today's video, which introduces the main concepts of this crucial GMAT topic. Enjoy!
