The table below shows the cost of riding in a taxi cab. what is the rate of change? miles driven taxi cost *$25 *$35 *$45 *$55 a) $2/mile b)$10/mile c)$1/mile d)$5/mile

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
