Answer 1

inclined line represents a and r.0 a is a straight line ll to x axis

Answer 2

Acceleration

Explanation:

The picture is missing in the question. Please refer to the attached picture for the graph.

Acceleration is marked along the y axis and time is taken along the x axis.

Acceleration is positive in quadrant I. You can see it at time 12 seconds to 16 seconds in the graph.

Retardation or negative acceleration can be see in quadrant IV. At 0 seconds to 7 seconds.

Zero acceleration is see on points along the X axis. 8 to 12 seconds, and beyond 16 seconds.
