Question

The midpoint of Gh is M -6,-3. One endpoint is H -4,4. Find the coordinates of endpoint G.

Answer 1

let the points of G be (a,b)

mid point of GH =(-6,-3)

point of H =(-4,4)

now,

for x coordinate,

-6=(a-4)/2

or, a-4 =-12

or, a=-8

for y coordinate,

-3=(b+4)/2

or, -6=b+4

or, b=-10

therefore, the coordinate of G is (-8,-10)
