Answer 2

(3,2)
(3,3)
(2,2)
(2,3)

these are the answers

Answer 3

\[x_{midd} = \frac{ (x_1 + x_2) }{ 2 }\]
\[y_{midd} = \frac{ (y_1 + y_2) }{ 2 }\]

Answer 4

so i just add the point they are at so if x was at -4 i would put it as -4-n?

Answer 5

just as writing the equation.

Answer 6

\[x_{midd} = \frac{ -2+8 }{ 2 } = ?\]

Answer 7

add coordinates of x term

Answer 8

oh ok

Answer 9

as told by @sangya21

Answer 10

=3?

Answer 11

Correct. So what will be the y?

Answer 12

correct :)

Answer 13

give me a second please

Answer 14

6?

Answer 15

how would it be 6?

Answer 17

\[y_{midd} = \frac{ 8+(-4) }{ 2 } = \frac{ 8-4 }{ 2 }\]

Answer 18

look at the second y

Answer 19

you would be subracting a negative so it would technically be adding the 4 to it would be 12?
