Question 416502
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+5}}} 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+b}}} where the slope {{{m = 12}}} and the y-intercept {{{b = 5}}}.
When you graph this function {{{y = 12x+5}}} it looks like this:
{{{graph(400,400,-2,5,-2,20, 12x+5)}}}
