Question

I need help with a question. I have plenty of time to work things out with someone if they are patient. I'm smart but I work slow, problem is in a reply.

Answer 1

The midpoint of line UV is (5, -11). The coordinates of one endpoint are U(3,5). Find the coordinates of endpoint V.

Answer 2

we can use an equation or we can think
your choice

Answer 3

Im sure we would get farther using the equation. I dont even think I know the equation

Answer 4

well then lets do it both ways, thinking is more understanding, the equation is just a math teacher way

Answer 5

endpoint is (3,5) mid point it (5, -11)

Answer 6

correct.

Answer 7

how many steps from 3 to 5 in the x direction?

Answer 8

3 is the x coordinate, 5 is the y coordinate. i dont know how i would go in the x direction

Answer 9

oh i see there are two fives there

Answer 10

OH
MY BAD HAHA I'M SORRY

Answer 11

+2

Answer 12

from the 3 in the first coordinate of \((3,5)\) to the 5 in the first coordinate of \((5,-11)\)

Answer 13

yeah right, +2
so you have to go another +2 from 5, and where are you?

Answer 14

why would you go 2 more from five?

Answer 15

because \((5,-11)\) is half way between one end point and the other

Answer 16

are we looking for distance to the endpoint or are we looking for the coordinates to the endpoint

Answer 17

7

Answer 18

7 is the answer, i have no idea what im doing so i'll just go with you. sorry

Answer 19

yes , so first coordinate of the other endpoint is 7

Answer 20

Wait wait wait

Answer 21

ok i will wait
but first, to answer your question about what we are looking for, the question states
Find the coordinates of endpoint V.

Answer 22

Yes i was just making sure you knew what we were looking for. i knew what we were searching for

Answer 23

ok so from 3 to 5 in the x direction is 2, go another 2 units get to 7

Answer 24

but why would you go 2 more from 5

Answer 25

thats what im not getting

Answer 26

i know thats how far it is from x1 to x2 but

Answer 27

because \((5,-11)\) is half way
you went 2 units, that is half way
to go all the way, go another 2 units

Answer 28

arent you supposed to divide them by two before you determine the coordinate

Answer 29

i may be wrong nut i think i remember a formula like that

Answer 30

yes, we will use the formula second
but don't forget we have one endpoint and one midpoint, not two endpoints

Answer 31

i think you are confusing a similar formula bland

Answer 32

if you like we can skip the think method and go right to the formula method

Answer 33

OH ok yeah wrong formula

Answer 34

im sorry about this satellite i just like to be 100% sure.

Answer 35

x coordinate is 7

Answer 36

no it is okay, and you might have the formula correct

Answer 37

got that, next step.

Answer 38

yes, exactly
now we do the same for the y

Answer 39

maybe visualize it
