Question

M is the midpoint of.
Find the coordinates of B given A(4,-2) and M(4,7).

Answer 1

M is the midpoint with the line of AB with the line on top

Answer 2

Do you know the formula to find the coordinate of midpoint?

Answer 3

Note that the x value doesn't change, so all motion is along the y direction. The distance to the midpoint is nine, so nine more upward gives coordinate (4,16) as B.

Answer 4

????

Answer 5

will it be -1,2

Answer 6

So you neither know the midpoint formula nor understand AnimalAin's explanation?

Answer 7

From what AnimalAin explains: A(4,-2) and M(4,7)
Notice both x coordinates the same => B ( 4, ...)
Then since Δy = 7 + 2 = 9
=> y = 7 + 9 = 16

Answer 8

thus B ( 4, 16)

Answer 9

there isnt a 4,16 in the multipuly choice

Answer 10

Let me test by my way, but I'm pretty sure my friend's way correct!

Answer 11

wil it be -1,2

Answer 12

Both ways yield exactly same result B ( 4, 16)

Answer 13

You must have mixed up the result from some other question :(

Answer 14

yeah you right am sorry bro

Answer 15

Of course, I know it happens :P
And I also know myself and my friend :)
