Answer:
-1/2
Step-by-step explanation:
You mention a graph, but have not shared that graph. However, your presentation of two points on this line is sufficient for the calculation of the slope of the line joining the two points.
The points are (-2, 2) and (0, 1).
As we move from (-2, 2) to (0, 1), x increases by 2 and y decreases by 1.
Hence, the slope of this line is m = rise / run = -1/2.
