The answer would be C. When you calculate the mean, it includes every number for a certain period of time into things and averages it out. The median does not average out all the numbers.
Step-by-step explanation:

1. Y= -5/2x + 17/2 (slope intercept form)
2. Y= -3/2x + 13/2 (slope intercept form)
Answer:
m = 3/4
Step-by-step explanation:
A(3, 7)
B(7, 10)
As we move from A to B, we see x increasing by 4 to 7 and y increasing by 3 to 10. Thus the slope is
m = rise / run = 3/4
