Question

If A(-9, 4) and B(3, -2), find the midpoint of AB.

Answer 1

Mid point is (-3, 1)

Explanation:

Let mid point be M

`{ \boxed{ \sf{m = ( (x _(1) + x _(2) )/(2)} , \: (y _(1) + y _(2))/(2)) }} \\ \\ { \tt{m = ( ( - 9 + 3)/(2) , \: (4 - 2)/(2) )}} \\ \\ { \tt{m = ( ( - 6)/(2), \: (2)/(2) ) }} \\ \\ { \tt{m = ( - 3, \: 1)}}`

Answer 2

(-3,1)

Explanation:

The value of x
`(-9+3)/(2)` = -3

The value of y
`(4-2)/(2)` = 1
