This calculator allows you to plot multiple equations on a single graph, which can help in linear programming. All the equations are color-coded, so it is easy to distinguish them from one another.

To plot a graph from its equation, substitute different values of 𝑥 into the equation to give the corresponding 𝑦-coordinates. The pairs of 𝑥 and 𝑦 values can be recorded in a table.

INTERPOL=BOXT20 specifies a box plot with tops and bottoms on its whiskers, and the high and low bounds at the 80th and 20th percentiles. CO= colors the boxes and whiskers. BWIDTH= affects the width ...
