Answer: The answer for both is infinity. You might want to recheck the question as it is not very common but if the question is correct this is the answer to it:
Explanation:
1. Using the formula m = y2 - y1 / x2 - x1
m = 1 - 1 / -3 -(-3)
m = 0/0
m = infinity
2. Using the formula m = y2 - y1 / x2 - x1
m = -14-(-14) / 7-7
m = 0/0
m = infinity.
