3.25 would Raquel to 47 so 20
.50 x 15 = 7.5. This is the total amount of miles he was charged.
7.5 + 3.00 (the base charged) = 10.50
Given line ax+by=c and point (h, k), the perpendicular line through (h, k) can be written as
b(x-h) -a(y-k) = 0
In order for this to be in standard form, it must be rearranged somewhat, and any common factors removed.
We can start with
20(x-8) -5(y-3) = 0
4x -32 -y +3 = 0
4x -y = 29
The standard-form equation of the desired line through (8, 3) is
4x -y = 29
The answer would be c because you cannot add unlike variables so the real answer should be 2j+2k, but b/c it's not an answer choice the answer is c)
