Q1 of 15 Page 179

Let's draw a graph of time and distance on the graph paper based on the information given below and find the distance covered in 4 hrs and find how long it will take to cover 150 km.

Let 1 hour = length of 5 sides of the smallest squares along x-axis, i.e., x-axis represents the Time (in hours).

And 25 km = length of 5 sides of the smallest square along y-axis, i.e., y-axis represent the distance (in km).



The given data are collinear, i.e., meet on a single line; we will call it a linear line.


(i) We will find the distance covered in 4 hrs


From the graph we can see that drawing a line from 4 on the x-axis to the linear line, we will mark this point it is (4,100).


So the distance covered in 4 hrs is 100 km.


(ii) We will find how long it will take to cover 150 km


From the graph we can see that drawing a line from 150 on the y-axis to the linear line, we will mark this point it is (6,150).


So the time taken to cover 150km is 4 hours.

Let's write 4 collinear points on a graph sheet and write the coordinates of the points. Similarly, plotting the points on the graph sheet and joining them we get some pictures. What will we call that?

I bought 4 exercise books for Rs. 20

Let's write the number and price of exercise books on the following table and draw a graph from the data. Let's find out the price of 6 exercise books and also find out the number of exercise books for Rs. 45 from the graph.

(i) For the graph paper beside we consider 1 unit=length of 2 sides of the smallest squares along both the axes. Let’s write the coordinates of the points.


(ii) Let’s find which three points are collinear.


(iii) Let’s find three points which are not collinear.

Let’s plot the points representing the coordinates (1,0), (2,1), (3,3), (1,3), (2,5) and (0,0) on the graph paper.
