-------------------
A linear function has the following format:

In which
- m is the slope, that is, the rate of change.
- b is the y-intercept, that is, the value of y when x = 0.
In this problem:
- Fixed cost of $9 per month,  . .
- Cost of $2 for each delivery, thus  . .

<span>4.375×10 = 43.75
</span><span>1 7/8 = 15/8 = 1.875
</span>1.428×10 = 14.28
so order from <span>Least to greatest:
</span>0.25 inches, 1.5 inches, 1 7/8 inches, 1.428×10 inches and <span>4.375×10 inches</span>
