Problem
A city taxi company charges a fixed booking fee in addition to a charge per kilometre. For a ride of x km, the total fare y (in rupees) is governed by the linear equation 7x−y+50=0.
(a) Using x=0,2,4,6,8, find the corresponding values of y.
(b) Plot the points obtained in part (a) on a graph sheet and draw the straight line that represents the fare rule.
(c) Use your graph to estimate the distance, correct to the nearest half-kilometre, for which the fare will be Rs 120.
