Well, let's recall what well, actually, let's first look at the following plot. So, again, the red describes the absence and the purple describes the presence of that uncompetitive inhibitor. And notice what happens. Essentially, we take the curve and we shift it upward. And notice the slope doesn't change because these lines are parallel. What changes is the X coordinate value, where the line intersects the X axis and the Y coordinate value, the Y intercept.
