Question

The graphs represent Daniel's ride to the ballpark. Describe Daniel's speed as he gets closer to the park. Justify.

Answer 1

B) decreasing; the slope of the line between D and E is negative.
you can rule A out because the graph isn't constant.
You can rule C out because the slope between DandE is going downward (negative slope)
and you can rule D out because the line between DandE is a straight line so it's identified and again its moving downward so it's negative

Answer 2

Before we choose the answers, lets define:

Constant: When the graph has a straight line, because the constant of proportionality wouldn't change. 
Decreasing: Going from up to down, or otherwise known as a negative correlation. 
Increasing: Going from down to up. Values increase. 

B would be the answer since from D to E, it's decreasing, and becoming negative.
