Please help!

A point moves in the plane of two perpendicular lines so that the product of its distances from the lines always is 12 when the point is 4 units from one of the lines, its distance from that line is decreasing at the rate of 2 units/min. At what rate is the distance from the other line changing at that moment?

I'm not sure how this situation would look so if someone could draw or make a diagram/graph for me (on Desmos or something), I would really appreciate it!
