To find the perpendicular slope of a line, just reciprocate its slope, and for finding the line parallel to it, according to purplemath.com:
"In numbers, if the one line's slope is m = 4/5, then the perpendicular line's slope will be m = –5/4. If the one line's slope is m = –2, then the perpendicular line's slope will be m =1/2. To answer this question, I'll find the slopes. Since these two lines have identical slopes, then these lines are parallel<span>."
I hope my answer has come to your help. God bless and have a nice day ahead!

Answer: 128 pages are text
Step-by-step explanation:
Answer:
can you please clarify your question? and it would be y=mx+b
b is you flat rate and m is per mile
27x - 144 + 15 = 6x - 24
27x - 129 = 6x - 24
+129 +129
--------- --------
0 105
27x = 6x + 105
-6x -6x
----- ------
21x 0
21x = 105
21x/21 = 105/21
x = 5
