Answer:
2
Explanation:
Step 1. Find two points that are easy to read. That means the point is on the intersection of grid lines.
For example, pick (0, -2) and (1, 0).
Step 2.
slope = (difference in y)/(difference in x)
difference in y is the difference of the y-coordinates.
difference in x is the difference of the x-coordinates.
When you do these differences, you must subtract the x-coordinates and the y-coordinates in the same order.
slope = (-2 - 0)/(0 -1)
slope = -2/(-1)
slope = 2
