(i) Here, we take time on the x-axis and temperature on the y-axis.
Let us choose the following scale:
On x-axis: 1 cm = 1 hour
On y-axis: 1 cm = 1 °F
Now, let us plot the given points.
These points are joined to get the graphs representing the given information as shown in the figures below.
Scale:
On x axis: 1cm = 1 hour
On y-axis: 1 cm = 1 °F
(ii) Here, we take time on the x-axis and temperature on the y-axis.
Let us choose the following scale:
On x-axis: 1 cm = 2 hour
On y-axis: 1 cm = 1 °F
Now, let us plot the given points.
These points are joined to get the graphs representing the given information as shown in the figures below.
Scale:
On x axis: 1cm = 2 hour
On y-axis: 1 cm = 1 °F
