can't see the problem anymore.

on the scratchpad I see programming functions:

==
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({ range: [[-10, 10], [-10, 10]], scale: [18, 18], tickStep: 1, labelStep: 1, unityLabels: false, labelFormat: function( s ) { return "\\small{" + s + "}"; }, axisArrows: "<->" }); plot(function( x ) { return ( M * x + B ); }, [-10, 10], { stroke: "BLUE" }); circle( [X, Y], 1/4, { stroke: "none", fill: "#ff0000" } );

m = -1 / M

b = Y - ( -1 / M * X )
