Answer:
-167.2 ft/mile
Step-by-step explanation:
The "rise" is 1298 -1776 = -478 ft. The run is given as 15,098 ft, so the slope is ...
slope = rise/run = -478/15098 ≈ -0.0316598
For 5280 feet in 1 mile, that rate of change amounts to ...
-0.0316598×5280 ft ≈ -167.2 ft . . . per mile
slope is change in y over change in x
use 2 points from the table so -3,-21 and -6,-39
change in Y: -39 - -21 = -18
change in x = -6 - -3 = -3
slope = -18/-3 = 6
slope = 6
