Q2 of 15 Page 180

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.

In a graph the horizontal line is x-axis and the vertical line is y-axis, and the point of intersection of x and y axis is the origin (0,0).

So in any point the first number if x-coordinate and the second number is y-coordinate.


So the graph of the given points is as shown below.

(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.

(i) Let’s put the points (1,1), (2,2) and (3,3) on the graph paper and see whether they are collinear.

(ii) Let’s put three non collinear points on the graph paper.


(iii) Let’s put three more collinear points other than the above three collinear points on the graph paper and write their coordinates

Let’s see the graph on the graph paper beside and let’s find the answers to the questions below:


(i) Let’s write the relation between the number of guava and the price of guava from the graph.


(ii) Let’s write the price of 4 guavas.


(iii) Let’s write the number of guavas in Rs 30 from the graph.


(iv) Let’s write the number of guavas in Rs. 9


(v) Let’s write the price of 9 guavas from the graph.
