Create equations in two or more variables and graph them with appropriate labels and scales.
Build and graph a constraint equation or inequality
Problem
A student has \(\text{at}~\text{most}~60~\text{minutes}\). Standard problems \(x\) take \(4~\text{minutes}~\text{each}\) and challenge problems \(y\) take \(7~\text{minutes}~\text{each}\), with \(\text{both}~\text{counts}\) nonnegative integers. Build the constraint and graph its contextual feasible region using the displayed graphs, including boundary type, intercepts, and shading.
