Answer:
-138
Step-by-step explanation:
Distance between midpoint and point (-100) = -100 - (-119)
= 19
Since the [distance between the midpoint and point (-100)] and the [distance between the midpoint and point A] is the same, the distance between the midpoint and point A is also 19. You already know the midpoint is at -119. Since the midpoint is lower than point (-100), point A should be lower than point (-100).
Point A = -119 - 19
Point A = -138
