Answer

The slope of curve AA' is positive. Its slope increases as we move from A to A'. The slope of curve BB' is negative. Its slope decreases as we move from B to B'.

Work Step by Step

Positive slope means that the y value is increasing as we move along the curve. Increasing slope means that the slope is becoming steeper heading towards the positive y direction. Negative slope means that the y value is decreasing as we move along the curve. Decreasing slope means that the slope is becoming steeper heading towards the negative y direction.
