Coordinate Geometry Test Topics

The questions in the Coordinate Geometry Diagnostic Test are typical of those on the Math 2 test. In
this chapter, we’ll use these questions to review the coordinate geometry you’re expected to know.
We will also use these questions to demonstrate some effective problem-solving techniques,
alternative methods, and test-taking strategies that apply to coordinate geometry questions.

MIDPOINTS AND DISTANCES

Some of the more basic Math 2 coordinate geometry questions are ones that concern themselves
with the layout of the grid, the location of points, distances between them, midpoints, and so on.

Example 1 involves both distances and midpoints.
