Question 1. The number of litres of petrol you buy to fill a car's petrol tank will decide the amount you have to pay. Which is the independent variable here? Think about it?
Answer: Since the quantity of petrol is a requirement, and the amount of money spent is linked with the quantity of petrol, petrol is the independent variable.
In simple words: The amount of petrol you need decides how much money you pay. So, the petrol quantity is the independent factor.
Exam Tip: In cause-and-effect relationships, the independent variable is the one that is changed or controlled, and its changes influence the dependent variable.

Question 1. The following table gives the quantity of petrol and its cost?
Answer:
| No. of litres of petrol | 10 | 15 | 20 | 25 |
|---|---|---|---|---|
| Cost of petrol in Rs | 500 | 750 | 1000 | 1250 |
The following steps help to draw the graph:
I. Mark the number of litres of petrol along the horizontal axis.
II. Mark the cost of petrol (in rupees) along the y-axis.
III. Plot the given points: (10, 500); (15, 750); (20, 1000); (25, 1250).
IV. Join these points.
The graph formed is a straight line.
Yes, we can find the quantity of petrol available for Rs 800. For this, take a point on the y-axis at 800 (let's call this point A). Draw a line from point A parallel to the x-axis, until it meets the graph at point B. Now from point B, draw another line perpendicular to the x-axis. This line will touch the x-axis at a point (let's call it C) which corresponds to (16, 0).
Therefore, 16 litres of petrol can be bought for Rs 800.
In simple words: First, create a graph from the table data. To find how much petrol Rs 800 buys, locate 800 on the cost axis (y-axis). From there, draw a line across to the graph line, then draw a line down to the petrol axis (x-axis). The number on the petrol axis shows you the quantity.
Exam Tip: When using a graph to find values, always draw clear, straight lines from the known axis to the graph, and then from the graph to the unknown axis to ensure accurate readings.
