The answere would be twelve fifths of an hour. 12/5 of an hour
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.
First, recall that the equation of a line is
y = mx+b
where
m = slope
b = y-int
The key to this question is the details :
Horizontal line ---> This tells you that your slope is 0
y-int = 3.5 -----> In the equation above, b=3.5
Therefore,
y = 0x + 3.5
y = 0 + 3.5
y = 3.5
Hope it helps with your work
I really don’t know but I think I got it wrong
