To find the slope means = rise/run
To solve this, you need to isolate/get the variable "n" by itself in the equation:
Multiply 21 on both sides to get "n" by itself
Simplify the fraction
-18 = n
Since she started out with 40,000 miles, you have to subtract that from 44,800 miles. you end up with 4,800 miles. you then divide 4,800 miles by 800 miles and you end up with 6 as your answer.
