Question

The midpoint of CD is E(-1,0). One endpoint is C(5,2). What are the coordinates of the other endpoint!

Answer 1

the way to do this, is start at the endpoint (5,2)
first do the x (the first number)
you are at 5, you go to the middle point at -1
how far did you move ?

Answer 2

I don't even get this :/

Answer 3

me neither lol where dum xD

Answer 4

if you are at 5 and go one step smaller you get to 4

if you are at 5 and go some number of steps you get to -1

Answer 5

you are at 5, you go to the middle point at -1
how far did you move ?

Answer 6

6

Answer 7

yes, now go 6 more steps from -1 , where do you end up ?

Answer 8

5

Answer 9

we want to go smaller. we start at 5....go 6 (smaller) to -1. now go another 6 (smaller) to ?

Answer 10

-7

Answer 11

if we use subtraction, we go -1 - 6 = -7

Answer 12

so -7 is the x value of the other end point.

now the y value

we start at 2 and go to 0
how far did we move?

Answer 13

-2

Answer 14

now go another -2 form 0 to get the the other end point

Answer 15

(7,-2)?

Answer 16

although it is -7 for the x right ?

Answer 17

yes
