This is what the problem looks like: Find the slope and y-intercept of the line that is \color{GREEN}{\text{LINE_TYPE}} to \enspace \color{BLUE}{y = M_FRACM_SIGNx + B}\enspace and passes through the point \color{red}{(X, Y)}.

graphInit({

unityLabels: false,
labelFormat: function( s ) { return "\\small{" + s + "}"; },
