Answer #1

Use origin software to plot the graph.

Procedure

i) Input the data on x-axis and y-axis

ii) Select all and then plot

iii) when you click plot various options will be displayed. Select scatter and you will get the plot.

iv) Choose the best fit. Three spot coinciding through origin. And draw line as shown and find the slope.

v) Obtained slope is the answer.

All the steps are shown below.
