F: (8, 14)

Answer 1

@satellite73 @zepdrix @ganeshie8

Answer 2

midpoint of E and F is fairly clearly \((8,8)\) it is the average of each coordinate
add up and divide by 2

Answer 3

midpoint of \( (-1, 2), (8, 2)\) is \((\frac{8-1}{2},\frac{2+2}{2})=(\frac{7}{2},2)\)

Answer 4

so how is E & F (8,8)

Answer 5

the average of 2 and 14 is 8, i.e. \(\frac{2+14}{2}=\frac{16}{2}=8\)

Answer 6

as for the first coordinate, both numbers are the same, so that is a vertical line
or you can think that the average of 8 and 8 is 8

Answer 7

why does 8 + -1 = 9 / 2 = 9/2 why is it 8 - 1/2

Answer 8

i am pretty sure i didn't write either of those

Answer 9

\[\frac{ (8 - 1) }{ 2 } + \frac{ (2 + 2) }{ 2 } = (\frac{ 7 }{ 2 }, 2)\]

Answer 10

look at the third comment at the beginning

Answer 11

the average of 8 and -1 is \(\frac{7}{2}\)

Answer 12

and the average of 2 and 2 is 2

Answer 13

you just forgot to add the "+" an but -1 ---> (-1)
