Answer:
The coordinates of point B are (5,-3)
Step-by-step explanation:
we know that
The formula to calculate the midpoint between two points is equal to

In this problem
Point A is at (-5, -4) and point M is at (0, -3.5)

substitute in the formula

so
Solve for x_2

Solve for y_2

therefore
The coordinates of point B are (5,-3)
B.-1 because she started on the twelfth floor she walks down 2=10 and then back up 3=13 so she has walk down 1 flight to get back.
