Choose any 2 points from the table:
<span>*10----------------------$25
*15----------------------$35
*20----------------------$45
*25----------------------$55
and find the slope of the line. Supposing we focus on
</span>*15----------------------$35
*20----------------------$45
then:
$45-$35 $10
slope = m = ------------- = ---------- = $2/mile
20-15 5
5555555.5 × 2 = 11111111
