Is it possible that the lines could have the same slope?

Answer to Problem 105E
Due to difference in both unit of measurement slope might be shows different but can be numerically equal.
Explanation of Solution
Given information:
With the information shown in the graphs, is it possible to determine the slope of each line? Is it possible that the lines could have the same slope? Explain.
Calculation:
Consider the given graphs.
From the graphs it is not possible to determine the slope of each line. Because there is no unit mentioned on
It may be possible that both line have same slope as per,
The above formula shows that slope is depends on
Hence due to difference in both unit of measurement slope might be shows different but can be numerically equal.
