This exercise will focus on coordinate geometry. Coordinate geometry problems are those that use number lines (x and y axis) and geometric shapes like triangles or squares. Draw diagrams in your test booklet to help solve these problems.

Topics in coordinate geometry include:

Midpoint formula
Slope of lines
Equations for lines
Distance formula

Review the following resources listed below and then do a practice set.
