Answer:
m = -8/3
Step-by-step explanation:
Keep in mind that slope is defined as m = rise / run, or, alternatively,
m = (change in y ) / (change in x).
If we start at (-10, 8) and move to (-4, -8),
the x coordinate is seen to increase by 6 from -10 to -4, and
the y coordinate decrease by 16 from 8 to -8.
Thus, the slope of the line segment connecting these two points is
m = -16 / 6, or m = - 8/3
