Question

The midpoint of AB ‾ AB is M ( 0 , 3 ) M(0,3). If the coordinates of A A are ( 4 , − 1 ) (4,−1), what are the coordinates of B B?

Answer 1

Using the midpoint concept, it is found that the coordinates of B are:

(-4,7).

What is the midpoint concept?

The mid-point between two points is the halfway point between them, and is found using the mean of the coordinates.

Since M is the midpoint of AB, the x-coordinate of B is found as follows:

0 = (4 + x)/2

4 + x = 0

x = -4.

The y-coordinate is found as follows:

3 = (-1 + y)/2

y - 1 = 6

y = 7.

The coordinates of B are:

(-4,7).
