Answer:2

Explanation:

Answer 2

Choose any 2 points from the table:

*10----------------------$25
*15----------------------$35
*20----------------------$45
*25----------------------$55

and find the slope of the line. Supposing we focus on

*15----------------------$35
*20----------------------$45

then:
$45-$35 $10
slope = m = ------------- = ---------- = $2/mile
20-15 5
