Question

How to find the midpoint of (-1,3) and 7(,-1)

Answer 1

midpoint of the points
`(x_1,y_1)` and
`(x_2,y_2)` is

`((x_1+x_2)/(2),(y_1+y_2)/(2))`

in this case

we have (-1,3) and (7,-1)
the midpoint will be

`((-1+7)/(2),(3-1)/(2))`
simplify

`((6)/(2),(2)/(2))`
simplify

`(3,1)`

the midpoint is
`(3,1)`

Answer 2

midpoint formula : (x1 + x2) / 2 , (y1 + y2) / 2
(-1,3)....x1 = -1 and y1 = 3
(7,-1)...x2 = 7 and y2 = -1
now we sub and solve
m = (-1 + 7) / 2 , (3 - 1) / 2
m = (6/2, 2/2)...reduce
m = (3,1) <==
