Solution
The correct option is D 7 units
The starting point is on the x-axis and it lies 2 units to the left of y-axis. This point is A(-2, 0), as shown on the graph.
If we move from point A to the y-axis, we cover a distance of 2 units.
Next, we move 5 units to the right, i.e. along the x-axis, to reach the final point B.
In total, we cover a distance of 2 + 5 = 7 units.
