If gh has a midpoint at (5,5) with point H at (3,9), then the coordinate of point G is at (7, 1)
The formula for calculating the midpoint of GH is expressed as:
[tex]M(X, Y) = \frac{x_1+x_2}{2} , \frac{y_1+y_2}{2}[/tex]
Get the coordinate x1
X = x1+x2/2
5 = 3 + x2/2
5×2 = 3 + x2
10 = 3 + x2
x2 = 10-3
x2 = 7
Get the coordinate y2
Y = y1+y2/2
5 = 9 + y2/2
5×2 = 9 + y2
10 = 9 + y2
y2 = 10-9
y2 = 1
Hence the coordinate of point G is at (7, 1)
