Answer:
slope of line segment XY is -2.
Step-by-step explanation:
From the given graph, we have
coordinate of the point X is (-1,3)
coordinate of the point y is (1,-1)
The slope of a line through the point
is given by

Here, we have

On substituting these value in the above formula of slope, we get

Therefore, the slope of line segment XY is -2.
