Answer 2

if u have points (a,b) and (c,d) the mid point has coordinates
\[ \large (\frac{a+c}{2},\frac{b+d}{2}) \]
can u go on from here?

Answer 3

i'll try

Answer 4

tell me if u get stuck

Answer 5

i'm stuck

Answer 6

look there is an easier way



so subtract 3-2 = 1 for x

and 0--4 = 4 for y

hten to get b just add 1 to 3 to find x

and 4 to 0 to find y
