Final answer:
To adjust the steepness of the red segment, drag the red point downward to make it less steep than the blue segment, and drag it upward to make it more steep than the green segment.
Step-by-step explanation:
To make the red segment less steep than the blue segment and more steep than the green segment, we need to adjust the slope of the red segment. Dragging the red point downward will make the red segment less steep compared to the blue segment. Dragging the red point upward will make the red segment more steep compared to the green segment.
