1) Km increases, no effect on Vmax, same y-intercept, increasing slope,
increased substrate can overcome
2) Vmax decreases, y-intercepts increase, constant slope, increased
substrate cannot overcome
3) Km increases, Vmax decreases, y-intercepts increase, slope increases,
increased substrate cannot overcome
