What is the midpoint of the following coordinates:
1.a=(4,7) and b=(-3,11) m=
2.a=(-8,3) and b=(-6,-3) m=
for questions three and four we know a and the midpoint but need to find b or a for question 4.
3.a=(-8,5) and m=(-3,-5) b=
4.m=(5,7) and b=(9,-2) a=

answer as soon as possible.
32 points available.

To find the midpoint if you have the points
(x,y) and (z,t) and you wnat to finnd the midpoint you do
midpoint=()
so

1. (4,7) and (-3,11)
midpoint=( )=(1/2,9)
 

2. (-8,3) ad (-6,-3)
midpoint=()=(-7,7)

3. (-8,5) and (-3,-5)
(-3,-5)=()
so
-3=
-6=-8+x
2=x

-5=
-10=5+y
-15=y
B=(2,-15)

4. (9,-2) and (5,7)
(5,7)=()

5=
10=9+x
1=x

7=
14=-2+y
16=y

A=(1,16)

1. M=(1/2,9)
2. M=(-7,7)
3.B=(2,-15)
4. A=(1,16)
