then the point (x, y) is
(A) (-3, 6)
(B) (6, -6)
(C) (6, -12)
(D) (3, -3)​

Answer 1

Answer:

c. 6,-12

Step-by-step explanation:

applying formula

x1+x2/2=x

and. y1+y2/2=y

3=0+x/2 ..... x=6

-6=0+y/2.... y=-12

thus coordinate are

6,-12

Answer 2

Answer:

Please mark as brainlieast

Step-by-step explanation:

x1+x2/2=x

&

y1+y2/2=y

3=0+x/2 .......... x=6

-6=0+ y/2............ y= -12

Hence x= 6 & y= -12
