In the given graph, the letter that represents the point (4, 0) is _____.

• A

• B

• C

• D

Answer explanation

In the point (4, 0), 4 is the x-coordinate and 0 is the y-coordinate. In the given graph, point A represents (4, 0). On the graph, the point B represents (4, 4), point C represents (0, 4) and point D represents (0, 0). Hence option 1 is the right answer.

The distance between city P and city Q is 100 km. The given graph shows the journey of two buses from city P to city Q. When the bus 2 reaches city Q, how far away is bus 1 from city Q?

• 10 km

• 20 km

• 30 km

• 40 km

Answer explanation

In the graph we can see that bus 2 reached city Q at 12:00 PM. At this time, bus 1 has covered a distance of 70 km. City Q is at distance of 100 km from City P. So, 100 km - 70 km = 30 km Therefore, bus 1 is 30 km away from city Q. Hence option 3 is the right answer.

The distance between city P and city Q is 100 km. The given graph shows the journey of two buses from city P to city Q. What was the speed of bus 1 before stopping at 10:00 AM in morning?

• 10 km/hour

• 20 km/hour

• 30 km/hour

• 40 km/hour

Answer explanation

In the graph, we can see that before stopping at 10:00 AM, bus 1 has travelled a distance of 40 km in 2 hour. Since Speed = Distance/ Time So, speed of bus 1 = 40/2 = 20 km/hour. Hence option 2 is the right answer.

Complete the given table and draw a graph for it. Click on 'Yes' when it is completed.

• Yes

• No

Answer explanation

We first need to find the y-coordinates and complete the table. Since y = x - 2 For x = 0, y = 0 - 2 = -2 For x = 1, y = 1 - 2 = -1 For x = 2, y = 2 - 2 = 0 For x = 3, y = 3 - 2 = 1 For x = 4, y = 4 - 2 = 2 We now need to plot the points (0, -2), (1, -1), (2, 0), (3, 1) and (4, 2) as done in the following graph.
