Question

The endpoints of CD are C(3,

5) and D(7, 9).
The coordinates of the
midpoint M of CD are

Answer 1

Answer: M(5,7)

Explanation:

`\displaystyle\\C(3,5)\ \ \ \ \ D(7,9)\ \ \ \ \ M(x_M,y_M)=?\\\\M(x_M,y_M)=((3+7)/(2),(9+5)/(2))\\\\ M(x_M,y_M)=((10)/(2),(14)/(2) )\\\\ M(x_M,y_M)=(5,7)`

Answer 2

M = (x1 + x2)/2 , (y1 + y2)/2
M = (3+7)/2 , (5+9)/2
M = (10/2 , 14/2)
M = (5, 7)
