Question

The midpoint of AB is M(0, -3). If the coordinates of A are

(2, -5), what are the coordinates of B?
Answer:

Answer 1

(-2, -1)

Explanation:

To get the coordinates of B, you need to double the distance from the midpoint to A. The difference of 2 and 0 is 2, and the difference between -5 and -3 is 2. So you need to move 2 along the x and y axis. That would give you (2, -1)
