Answer: The correct option is (A) 4.
Step-by-step explanation: We are given to find the slope of the graph shown in the figure.
We can see that the graph is a straight line.
Also, the line passes through the points
and

We know the slope of a straight line passing through the points (a, b) and (c, d) is given by

Therefore, the slope of the given line is

Thus, the required slope of the graph is 4.
Option (A) is correct.
