Answer:
-4
Step-by-step explanation:
Parallel lines have the same slope throughout. Find the slope of the line connecting the given points and you will then have the answer to this question.
Moving from (-2,6) to (0,-2)
we see that x (the "run") increases by 2 and y (the "rise") decreases by 8.
Thus, the slope of this line is m = rise / run = m = -8/2 or m = -4
