The temperature of a place measured from 6 a.m. to 6 p.m. at intervals of 2 hours is given below:

Draw a graph to represent the above information. Using this graph, find the following:

Time before noon, when the temperature was ${20}^{\mathrm{o}}\mathrm{C}$.

The temperature of a place measured from 6 a.m. to 6 p.m. at intervals of 2 hours is given below:

Draw a graph to represent the above information. Using this graph, find the following:

Time, to nearest minute, when the temperature was $25°\mathrm{C}$.

Given below is a (able of the stretch of a spring in a balance. Draw a graph on the basis of this table.

A car travelled for 14 hours, starting at 4:00 hours. The speed of the car at different hours is given below:

Draw a graph represent the above data:

The following table shows the sales of a commodity during the years $2004-2009$.

Draw a graph to represent the above data.

Draw a graph to convert $1$ to $7$ miles to kilometres given that $1$ mile $= 1.6 \mathrm{km}$.

6. The table given alongside gives the temperature in ${}^{\mathrm{o}}\mathrm{C}$ and its corresponding value in ${}^{\mathrm{o}}\mathrm{F}$.

Draw a graph by taking temperature in ${}^{\mathrm{o}}\mathrm{C}$ on X-axis and ${}^{\mathrm{o}}\mathrm{F}$ on Y-axis.

The given table shows the displacement of a body at different times. Draw a displacement-time graph to describe the motion of the body.
