Draw a linear graph for the following data: x 0 2 3 4 5 6 y 1 . 5 4 . 8 5 5 . 4 5 . 8 6 . 9

We know that, The graph representing two quantities in direct variation is a straight line graph called a linear graph. To plot the given points on a graph sheet, Draw the X & Y co-ordinate axis on a Cartesian plane. Plot the ordered pair on the coordinate plane. Then, join the points using the ruler to get a straight line which is the required linear graph. Scale for the graph X-axis: 1 division = 1 unit and Y-axis: 1 division = 10 units. Therefore, the obtained graph is According to the question, given to draw linear graph., but we get a line graph for the given data.

The runs scored by a cricket team during first five overs is as follows: Overs 1 s t 2 n d 3 r d 4 t h 5 t h Runs 3 2 4 8 6 Plot the graph and find the run rate during the fifth over.

We know that, The graph representing two quantities in direct variation is a straight line graph called a linear graph. To plot the given points on a graph sheet, Draw the X & Y co-ordinate axis on a Cartesian plane. Plot the ordered pair on the coordinate plane. Then, join the points using the ruler to get a straight line which is the required linear graph. Scale for the graph X-axis (overs): 1 division = 1 unit and Y-axis (runs): 1 division = 1 units. Hence, the obtained linear graph is The Run rate during fifth over is 6 runs, that is 6 6

The following table shows the rainfall recorded for the same duration in two cities: Week 1 Week 2 Week 3 Week 4 Week 5 City A 1 . 2 m m 0 . 8 m m 2 . 5 m m 2 . 1 m m 3 m m City B 1 . 3 m m 1 . 2 m m 2 . 0 m m 2 . 1 m m 3 . 5 m m Plot the graph. Find the average rainfall for both the cities.

We know that, A line graph displays quantitative values over a specified time interval. To plot the given points on a graph sheet, Draw the X & Y co-ordinate axis on a Cartesian plane. Plot the points Scale for the graph X-axis (weeks): 1 division = 1 unit and Y-axis (cities): 1 division = 0 . 5 units. Average = S u m N u m b e r o f w e e k s Average rainfall for city A = 1 . 2 + 0 . 8 + 2 . 5 + 2 . 1 + 3 5 = 9 . 6 5 = 1 . 92 Therefore, average rainfall of city ( A ) = 1 . 92 Average rainfall for city B = 1 . 3 + 1 . 2 + 2 . 0 + 2 . 1 + 3 . 5 5 = 10 . 1 5 = 2 . 02 Therefore, average rainfall of city ( B ) = 2 . 02
