I THINK IT IS B
B) D(X)= X-8x4
Answer:
The slope:

Step-by-step explanation:
-To determine the slope of the following points shown, you need this formula:

(
represents the slope,
represents the first coordinate and
represents the second coordinate)
-Apply the following points to the formula:

Then, solve:


So, the slope is
.
256.5/18= 14.25
(14.25x2)+(18x2)= 64.5m
10 miles=52800 feet (I know for sure)
