Question

The mid point of AB IS M (5,2). if the coordinate of A are (6,-5) what are the coordinate of B.

Answer 1

The coordinate of B are
`(4,9)`

Explanation:

Let coordinate of B be
`(x,y)`

We have

`\left ( (6+x)/(2),(-5+y)/(2) \right )=(5,2)\\\\\left ( 6+x,-5+y \right )=(10,4)\\\\\left ( x,y \right )=(4,9)`

The coordinate of B are
`(4,9)`
