We need to draw the line graph for the given data. Steps of construction of line graph: On a graph, draw two lines perpendicular to each other intersecting at O. The horizontal line is x-axis and vertical line is y-axis. Mark points at equal intervals along x-axis and write the names of the data items whose values are to be marked. Along the y-axis, choose an appropriate scale considering the given values. Now, make the points. Join each point with the successive point using a ruler. Thus, a line graph is obtained. Let us mark over on x-axis and runs scored on y-axis, We take scale, Along horizontal: 1 unit = Over Along vertical line: 1 unit = Runs scored Hence, the line graph for the given data is shown above.

Let us mark quantity on x-axis and cost on y-axis, We take scale, Along horizontal: 1 unit = 2 kg Along vertical line: 1 unit = ₹ 100 Hence, the line graph for the given data is shown above.

Plot the point x , y given in the following table on a graph paper. x 3 2 0 1 4 5 y 2 4 3 5 6 1

Given, x 3 2 0 1 4 5 y 2 4 3 5 6 1 We need to plot the points on a graph paper. An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses. It helps to locate a point on the Cartesian plane for better visual comprehension. Hence, the graph is shown above.
