Answer 1

The slope is the amount it will cost you per mile, in addition to the flat fee represented by the y-intercept.  (The cost before driving any miles.)

So b. is the  correct answer as;

$25 is the cost per day to rent the car and $0.15 is the cost per mile.

Answer 2

c=25+0.15x
c = 0.15x + 25

means 25 is cost per day  and 0.25 cents is the cost per mile driven

answer is 
b.
$25 is the cost per day to rent the car and $0.15 is the cost per mile.
