The total cost,y , for a taxi ride depends on the number of miles traveled,x .

Question

Part A:  Find the slope and 

-intercept for the linear relationship.  Show all work.

Part B:  Write the equation that is expressed by the linear relationship

0 miles for $2.50 and 1 mile $5.00 5 miles $15.00 and 10 mile $27.50

Answer 1

(0,$2.50)

(1, $5)

(5, $15)

(10, $27.50)

THe slope is $2.50. The intercept is also $2.50 since (0, $2.50) is on the line.

The linear function is then y = $2.50 x + 2.50
