Given that, An auto charges ₹ 15 for first kilometer and ₹ 8 each for each subsequent kilometer. For a distance of ‘x’ km. an amount of ₹ ‘y’ is paid.
⇒ the extra charge for first kilometer apart from 8-
= 15-8 = Rs.7
⇒ y = 8x + 7 is the linear equation.
For graph, we’ll first make the table of solutions by putting some random values of x and thereafter we’ll find corresponding values of y and then we’ll plot these points on graph, join them and extend them in straight line to find the graph.
(Note: ∵ equation is linear graph will always be straight line.)
Table of solutions for the given equation-
Now, from the graph, distance travelled if the fare paid is Rs.55
is 6 km (pt. E)
And the money to be paid for 7 kilometers is Rs. 63. (pt. F)
