Introduction

The following graph shows the temperature forecast and the actual temperature for each day of a week.

On which days was the forecast temperature the same as the actual temperature.

The following graph shows the temperature of a patient in a hospital, recorded every hour.

The patient’s temperature was the same two times during the period given. What were these two times?

For an experiment in Botany, two different plants, plant $A$ and plant $B$ were grown under similar laboratory conditions. Their heights were measured at the end of each week for $3$ weeks. The results are shown by the following graph.

How high was Plant $A$ after (i) $2$ weeks (ii) $3$ weeks?

A courier-person cycles from a town to a neighbouring suburban area to deliver a parcel to a merchant. His distance from the town at different times is shown by the following graph. If he rides fastest during $t \mathrm{a}.\mathrm{m.}$ to $\left(t+1\right) \mathrm{a}.\mathrm{m.}$ find $t$?

A courier-person cycles from a town to a neighbouring suburban area to deliver a parcel to a merchant. His distance from the town at different times is shown by the following graph.

If the distance of the place of merchant from the town is $x \mathrm{km}$, write $x$ as the final answer.

A courier-person cycle from a town to a neighbouring suburban area to deliver a parcel to a merchant. His distance from the town at different times is shown by the following graph.

If the person took $x$ hours to travel, write the value of $x$ as the final answer.

A courier-person cycle from a town to a neighbouring suburban area to deliver a parcel to a merchant. His distance from the town at different times is shown by the following graph.

If the scale for the time axis is $1 \mathrm{hour}=k \mathrm{units}$, then find the value of $k$.

Use the table for population (in thousands) of men and women in a village in different years, to draw a linear graph:

The following graph shows the temperature forecast and the actual temperature for each day of a week. On which day did the actual temperature differ the most from the forecast temperature?

The following graph shows the temperature forecast and the actual temperature for each day of a week.

If the minimum actual temperature during the week was $k°C$, then find the value of $k$.

The following graph shows the temperature forecast and the actual temperature for each day of a week.

If the maximum forecast temperature during the week was $x°\mathrm{C}$, then find $x$.

For an experiment in Botany, two different plants, plant $A$ and plant $B$ were grown under similar laboratory conditions. Their heights were measured at the end of each week for $3$ weeks. The results are shown by the following graph.

Write the correct answer from the given options: $\left(\mathrm{First} /\mathrm{Second} /\mathrm{Third}\right)$ week.

During which week did Plant $B$ grow least?

For an experiment in Botany, two different plants, Plant $A$ and Plant $B$ were grown under similar laboratory conditions. Their heights were measured at the end of each week for $3$ weeks. The results are shown by the following graph. If the growth of Plant $A$ was the most in Week $x$, then write the value of $x$.

For an experiment in Botany, two different plants, plant $\mathrm{A}$and plant $\mathrm{B}$ were grown under similar laboratory conditions. Their heights were measured at the end of each week for $3$ weeks. The results are shown by the following graph.

If the plant $\mathrm{B}$ grew from the end of the $2^{\mathrm{nd}}$ week to the end of the $3^{\mathrm{rd}}$ week by $k \mathrm{cm}$, then find the value of $k$.

For an experiment in Botany, two different plants, plant $\mathrm{A}$and plant $\mathrm{B}$ were grown under similar laboratory conditions. Their heights were measured at the end of each week for $3$ weeks. The results are shown by the following graph.

If the height of plant $\mathrm{A}$ during $3^{\mathrm{rd}}$ week is $x \mathrm{cm}$, find $x$.

For an experiment in Botany, two different plants, plant $A$ and plant $B$ were grown under similar laboratory conditions. Their heights were measured at the end of each week for $3$ weeks. The results are shown by the following graph.

If the height of plant $B$ after $2$ weeks was $k \mathrm{cm}$, find the value of $k$.

The following line graph shows the yearly sales figures for a manufacturing company.

In which year was there the greatest difference between the sales as compared to its previous year.
