Question

What is the midpoint between the points (4, 82) and (6, 96)?
A. (2, 14)
B. (1, 7)
C. (5, 90)
D. (5, 89)

Answer 1

let mid point will be (x,y)

x1=4
x2=6
y1=82
y2=96

x=x1/2+x2/2
y=y1/2+y2/2

$x = \frac{4 + 6}{2} = 5$

$y = \frac{82 + 96}{2} = \frac{178}{2} = 89$

there fore mid point is (5,89)

option D) is right

Answer 2

The midpoint between the points (4,82) & (6,96) is ----

$( \frac{4 + 6}{2} ) \: (\frac{82 + 96}{2} ) \\ \\ = ( \frac{10}{2} ) \: ( \frac{178}{2} ) \\ \\ = (5) \: (89)$

The answer is ---- D. (5 , 89)
