The slope is of $13, which means that each new sign costs $13.
-----------------
A linear function has the following format:
In which
- m is the slope, which is the rate of change, that is, how much y changes when x changes by 1.
- b is the y-intercept.
-----------------
- In the linear function in this problem, we have two points (x,y): (5,72) and (15,202).
- The slope is given by the <u>change in y divided by the change in x</u>, thus:
- The slope is of $13, which means that each new sign costs $13.
