Answer: Not 100% sure but this is what I think.
-4/5
Step-by-step explanation:
(5, -1) (15, −9)
1Y - 2Y / 1X - 2X = SLOPE
-1 + 9 / 5 - 15 = 8/-10 = -8/10 = -4/5
 
        
             
        
        
        
Answer:
the runners have gone 20.8 times around the globe all together
Step-by-step explanation:
At the Bostom Marathon, we have a total of
N = 20,000 runners
We know that each runner ran a distance of
d = 26 miles
Therefore, the total distance travelled by all runners combined is:

We know that the circumference of the Earth is

Here we want to find how many times around the globe would the marathon runners have gone. This can be found by calculating the following ratio:

And substituting the values, we find:

So, the runners have  gone 20.8 times around the globe all together.
