Question

M is the midpoint of AB. If A is at (5, 7) and M is at (-3, -4), find the coordinates of B.

Answer 1

By mid point formula,

(x1+x2/2,y1+y2/2)

(5+x2/2,7+y2/2)=(-3,-4)

5+x2/2=-3 and 7+y2/2=-4

5+x2=-6 and 7+y2=-8

x2=-6-5 and y2=-8-7

x2=-11 and y2=-15.

Answer 2

Step-by-step explanation:

$Correct option is$

A(6,6)

Given points (9,5),(3,7)

Midpoint formula

[Midpoint is given as $(2x1+x^2,2y1,y2)(29+3,25+7)(212,212)=(6,6)$
