The variables \(x\) and \(y\) are related by a certain equation. This equation may be expressed in two forms suitable for drawing line graphs. The two graphs shown have different variables plotted at each axis. Given the coordinates of a point on each line, find the original equation relating \(x\) and \(y\).
