Question

The midpoint M of CD has coordinates (0,4). Point C has coordinates (0,5). Find the

coordinates of point D.
Write the coordinates as decimals or integers.

Answer 1

0,6

Explanation:

Answer 2

(0 ,3)

Explanation:

Midpoint = (0,4)

Endpoint C= (0,5)

Endpoint D = (?, ?)

`(0.4)=(x ,y)\\\\(0,5)=(x_1,y_1)\\\\(x_2,y_2)= ?\\\\x = (x_1+x_2)/(2)\\ \\0 = (0+x_2)/(2)\\ \\Cross\:Multiply\\0 =0+x_2\\0-0=x_2\\\\x_22 =0\\\\y = (y_1+y_2)/(2)\\ \\4 = (5+y_2)/(2)\\ \\Cross\: multiply\\8 =5+y_2\\\\8-5 =y_2\\\\3 =y_2`
