_____
When writing a fraction in plain text, parentheses are needed around the entire denominator. The order of operations tells you that a/bc = (a/b)c, not a/(bc).
14. B (4, -2)
15. I am not exactly sure about this one but I would say either A or B.
Answer:
x-intercept (-7,0)
y-intercept (0,2)
Step-by-step explanation:
A has fixed one time fee of $12 and if you go to it say "m" months you pay $28 for each month, so your total cost at A is really 12 + 28m.
B has a fixed one time fee of $20 and if you go to it "m" months you pay $26 for each month, so you total cost at B is 20 + 26m.
how many months for the cost to be the same?

well, since the cost for both is the same, we can just get A's, knowing that B is the same

I believe it is b)
Because you always do rise over the run and if it goes right then it is positive and if it goes left it is negative.
