Question

Find the midpoint of the line segment with end coordinates of:
(
1
,
7
)
and
(
3
,
−
2
)

Give coordinates as decimals where appropriate

Answer 1

Answer:

Let (x,y) be the mid point of given points (2,7)≡(x

1

,y

1

) and (12,−7)≡(x

2

,y

2

)

x=

2

x

1

+x

2

, y=

2

y

1

+y

2

∴x=

2

2+12

and y=

2

7−7

∴x=7 and y=0

∴(7,0) is the midpoint
