# Unit 2: Slope & Lines

# Picture This

Mathematical equations with more that one solution can be modeled using pictures. Most notably, on the GED®, those pictures take the form of lines. You should make it a goal to be an expert of graphing and analyzing lines to be best prepared to ace your math test.

## Get Ready!
