Letter B would be the answer.
2L + 2(1/2L) = 90
2L + L = 90
3L = 90
L = 30
(1/2)(30) = 15
W = 15
CHECK:
30 + 30 + 15 + 15 = 90
The Y values are the same, so the Y value for A would also be 3.
B is at x 0 and the midpoint is -4 so there are 4 units between the mid point and B. You need to subtract 4 units from the midpoint for A.
-4 - 4 = -8
Point A is located at (-8,3)
Answer:
13 units
Step-by-step explanation:
Points A(-1, -6) and B(-1, 7) both lie on the vertical line x=-1. That means the distance between them is the difference of their y-coordinates:
__
By -Ay = 7 -(-6) = 13
Segment AB is 13 units long.
