y=-0.7/x The lines of the graph are located in Quadrant II and Quadrant IV; asymptotic at 0.7. The Graph in Q II is asymptotic only at quadrant II; Q IV at quadrant IV. The line of reflection is diagonally crosses from QIII -> point of origin -> QI
More or less, y=-0.9/x has the same characteristic as y=-0.7/x but y=-0.9/x is asymptotic at 0.9
