Draw the graphs for the following tables of values, with suitable scales on the axes.

(a) Cost of apples

(b) Distance travelled by a car

(i) How much distance did the car cover during the period 7.30 a.m. to 8 a.m?

(ii) What was the time when the car had covered a distance of 100 km since it’s start?

(c) Interest on deposits for a year.

(i) Does the graph pass through the origin?

(ii) Use the graph to find the interest on Rs 2500 for a year.

(iii) To get an interest of Rs 280 per year, how much money should be deposited?

Steps to follow for Drawing the graph

1. Find the quantities to be plotted

2. Decide the quantities to betaken on x-axis and on y-axis.

3. Choose a scale.

4. Plot points.

5. Join the points

a) We can mark number of apples on x-axis and cost of apples in y-axis1. Find the quantities to be plotted

2. Decide the quantities to betaken on x-axis and on y-axis.

3. Choose a scale.

4. Plot points.

5. Join the points

b) We can mark timing on x-axis and distance covered in y-axis

i) 20 km

c)

i) Yes

iii) From the graph, we can infer that Rs3500 deposit is required to earned Rs 280 interest

Draw a graph for the following.
