Draw the graph of the following table of distance travelled by a car, with suitable scales on the axes. Time (in hours) 6 a . m . 7 a . m . 8 a . m . 9 a . m . Distance ( in km ) 40 80 120 160 How much distance did the car cover during the period 7 . 30 a . m . to 8 a . m . ?

Let us draw the graph by taking Time (in hours ) on x -axis and Distance (in km ) on y -axis. Now, for a suitable scale, We take x -axis as Time = 1 hour and y -axis as 1 unit = 40 km From the given data, the graph follows as below: We can observe from the above graph that the car covered a distance of 20 km during 7 : 30 a . m . to 8 a . m .

Draw the graphs of the following tables of distance travelled by a car, with suitable scales on the axes. Time (in hours) 6 a . m . 7 a . m . 8 a . m . 9 a . m . Distance ( in km ) 40 80 120 160 What was the time when the car had covered a distance of 100 km since its start?

Let us draw the graph by taking Time (in hours) on x -axis and Distance (in km ) on y -axis. Now, for a suitable scale, We take x -axis as Time and y -axis as 1 unit = 40 km From the given data, the graph follows as below: From the above graph, at 7 : 30 a . m . the car covered a distance of 100 km .

Draw the graph of the following table of interest on deposits for a year, with suitable scales on the axes. Deposit (in ₹) 1000 2000 3000 4000 5000 Simple Interest ( in ₹ ) 80 160 240 320 400

Let us draw the graph by taking Deposit ( ₹ ) on x -axis and Simple Interest ( ₹ ) on y -axis. Now, for a suitable scale, We take x -axis as 1 unit = ₹ 1000 and y -axis as 1 u n i t = ₹ 80 From the given data, the graph follows as below: Hence, the required graph is as shown above.

Draw a graph for the following. Is it a linear graph? Side of Square (in cm ) 2 3 4 5 6 Area (in cm 2 ) 4 9 16 25 36

Let us draw the graph by taking side of a square ( c m ) on x -axis and area ( c m 2 ) on y -axis. Now, for a suitable scale, We take x -axis as 1 unit = 1 cm and y -axis as 1 unit = 4 c m 2 . From the given data, the graph follows as below: Hence, it is not a linear graph.
