Question

The coordinates of the midpoint of line segment AB are (-2,4). If the coordinates of point A are (7,10), what are the coordinates of point B?

A) (-2 1/2,7) B) (5,6) C) (11,-2) D) (-11,-2)

Answer 1

@huneya

Answer 2

use the midpoint formula for this

Answer 3

ok

Answer 4

do you still need help and did you draw what it looks like?

Answer 5

Is the answer A?

Answer 6

no

Answer 7

Why isn't it A?

Answer 8

because a is the x is -2 is already in the midpoint coordinate

Answer 9

i didn't read the question right
to find the midpoint of a line segment
(x1 + x2)/2 , (Y1 + Y2) / 2

Answer 10

ok

Answer 11

-2+7/2, 4+10/2 SIMPLIFIES to 5/2, 14/2

Answer 12

I got 2.5 (2 1/2) + 7= 9.5

Answer 13

no u dont simply

Answer 14

Using the midpoint rule

(x+7)/2=-2 and (y+10)/2 = 4

x = -11 y = -2

B is Pt(-11,-2)

Answer 15

The coordinates of the midpoint of line segment AB are (-2,4). If the coordinates of point A are (7,10), what are the coordinates of point B?
LET (x1, y1) = (7,10) let B = (x2, y2)
(7 + x2)/2 = -2 (10 + y2) /2 = 4
can you finish this?

Answer 16

so, the answer is D?

Answer 17

yes

Answer 18

wow, that was tricky

Answer 19

Thanks to all!

Answer 20

not really
have to pay attention to what the question is asking and know what formula to apply.
example me ; if i read properly first would not ask if you already plot the coordinates

Answer 21

you are welcome
