Hello there.
<span>1 mile equals how many inches?
63360

Let's see how many pages he spellchecks in 1hrto start with,
20min is 1/3 of an hr so multiply both numbers by 3
20*3=60min or 1hr
14*3=42
So he spell checks 42 pages in an hour now let's multiply that by 5.5
1hr*5.5=5.5hrs
42*5.5=231
He spellchecks 231 pages in 5.5 hrs
The equation to find slope is
Y2 - Y1
-------------
X2 - X1
Lets plug in
-2 - 4
------------
4 - 3
Solve
-6/1
Your final slope is -6
