The answers are decreasing, constant, increasing, constant.
1. In section A, speed is decreasing as time is increasing.
2. In section B, speed is constant as time is increasing.
3. In section C, speed is increasing as time is increasing.
4. In section D, speed is Constant as time is increasing.
Looking at the Line graph,
At Y-axis, we have speed measurement in mph,
At X-axis, we have time measurement in minutes.
Therefore,
In section A,
As the line is a decreasing graph, showing that speed is decreasing as time is increasing.
In section B,
As the line is a straight line, showing that speed is constant as time is increasing.
In section C,
As the line is an increasing graph, showing that speed is increasing as time is increasing.
In section D,
As the line is a straight line, showing that speed is constant as time is increasing.
Hence, the answers are decreasing, constant, increasing, constant.
