Question 416502: Hi need some with the equation y=12x+5 with showing the total cost for ordering tickets on the phone for a certain outdoor concert. Tickets are $12.00 ea. and there is a one-time service fee of $5.00. Can the slope of this line be thought of as a rate? Explain.
Thanks for all your help :o)

You can put this solution on YOUR website!
In the given equation for the total cost (y) of x tickets at $12.0 per ticket plus a one-time service fee of $5.00 (y+=+12x%2B5 the slope of the line produced by graphing this equation is 12 and the slope of a linear equation can always be thought of as the rate of change.
Here you can think of the slope as the rate of change of the total cost with respect to the number of ticketes purchased.
The given equation is in the "slope-intercept" form y+=+mx%2Bb where the slope m+=+12 and the y-intercept b+=+5.
When you graph this function y+=+12x%2B5 it looks like this:
