The midpoint of AB is M(1, -4). If the coordinates of A are (-3,-6), what are the coordinates of B?
kramer

Answer:

The coordinates of B is (5,-2)

Step-by-step explanation:

In order to find the coordinates of B, you have to use midpoint formula. Then substitute the following values into the formula :

m = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )

Let (x1,y1) be A (-3,-6),

Let (x2,y2) be B,

Let midpoint be M (1,-4),

(1, - 4) =  (\frac{ - 3 + x2}{2} , \frac{ - 6 + y2}{2} )

by \: comparison, \:

\frac{ - 3 + x2}{2}  = 1

- 3 + x2 = 2

x2 = 5

\frac{ - 6 + y2}{2}  =  - 4

- 6 + y2 =  - 8

y2 =  - 2
