Question

Suppose that it costs $16 to place a classified advertisement in the newspaper, plus $6 for each line. Then the cost to place an adx lines long is given by y dollars, where y = 6x + 16.
Express as an ordered pair the fact that a 12 line ad costs $88.
(Simplify your answer. Type an ordered pair. Type an integer or a fraction.)

Answer 1

In the question, you were told:

x = # of lines in the ad

y = cost of ad, in dollars

So you're now told 12 lines costs $88.  

How do you write that as an ordered pair?  Do we write ordered pairs as (x,y) or (y,x)?
