Answer: The correct option is
(B)

Step-by-step explanation: We are given to find the slope of the straight line shown in the graph.
From the graph, we see that the line passes through the points (-6, 3) and (12, 6).
The SLOPE of a line passing through the points (a, b) and (c, d) is given by

Therefore, the slope of the given line is

Thus, the slope of the given line is

Option (B) is CORRECT.
