For the first question, the most appropriate answer is D, since it is when the distance ran remains the same, but the time is still ticking. Unless the time stops, the graph should always be going in an upwards direction.
For the second question the most accurate answer is A
For the third question, nonlinear decreasing seems to be the most appropriate answer since it is going down at a non addition/subtraction rate.
For the fourth question I am not too sure, but I strongly believe that the correct answer is D, since it is the only one that seems to have a negative direction to it!
And for the fifth and final question, the correct answer would certainly be C, It has a constant rate of change.
I really hope this helps you with your homework, and if you need me to do any explaining, please let me know and I will do so! Thank you!
