Question

Let x represent the number of adults entering the movie theater and let y represent the cost,in dollars,of admission to the movie theater.Write an equation to illustrate the relationship between the number of adults entering the theater and the cost in dollars for admission

Answer 1

y=9x

Explanation:

We are given that x is number of adults entering the theater, and that y is the total cost. When we look at the graph, one person is at 9 dollar, 2 people are at 18 dollars, so on and so forth. If we take 2 ordered pairs, in this case we can use (1,9) and (2,18) we do the slope formula. We will do (18-9)/(2-1)

then we get 9/1 meaning it is $9/1 ticket.

our equation is then going to be y=9x
