Question

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

A) constant; the slope of the line between points B and C is 0
B) decreasing; the slope of the line between points D and E is negative
C) increasing; the slope of the line between points D and E is positive
D) decreasing; the slope of the line between points D and E is undefined

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
