Could someone check my answer: the question is: The equation y= 12x +5 shows the total cost for

ordering tickets on the phone for a certain outdoor concert.
Tickets are $12 each, and there is a one-time service
fee of $5. Can the slope of this line be thought of as
a rate? Explain. I realize that it looks like it could be thought of as a rate but the definition of a rate states that it is ratio of two quantities that involve different units such as miles to gallons. So I am thinking that the slope would not be considered a rate because both numbers are the same unit (money)

no, it is a rate

think of the 12x as (12/1)x, that is,
it costs $12 per 1 ticket, so the 12 is the >b>rate of money per ticket, "two quantities that involve different units"
