the equation y=12x+5
has the same form as y = mx + 5
where m is the slope or the rate.
Slope is defined as (change of y)/(change of x)
In your case, the cost changes $12 per ticket, that is, a rate of $12/1 ticket
The equation y=12x+5 shows the total coat for ordering tickets on the phone for a certain outdoor concert. if the tickets are $12 each, & there is a one time service fee of $5, can the slope of this line be thought of as a rate??
Please explain this.
