**Classifications**

Developed as part of the Math Circles of Inquiry project, this short module explores a graphical solution to a system of equations. Students answer questions about lemonade sales and physically stand on the coordinates of a giant grid in order to see that plotting two equations on the same set of axes can give useful information. They will also gain experience in linear equation formats other than slope-intercept form and explore what the intersection points of the lines in a system of equations means.

Topics covered: Algebra / Arithmetic, Geometry

Mathematical practices: MP1 – Make sense of problems and persevere in solving them., MP4 – Model with mathematics.
