Question

I’m having trouble finding the midpoint of the segment joining the point P1 and P2
P1 = (3,4)
P2 = (-5,7)
Could someone help me please.

Answer 1

Mid point of the segment joining two points with the coordinates (x1,y1) and (x2,y2) is =( (x1+x2)/2 , (y1+y2)/2 )

 

 

two points are P1 = (3,4)  &  P2 = (-5,7)

Coordinates of the mid point of the segment joining the point P1 and P2

 

= (  ( 3+(-5)) /2 ,  ( 4+7)/2  )

= (   -2/2 , 11/2 )

= (-1, 5 1/2 )

= (-1,5.5)

Answer 2

mid = ( (x₁ + x₂)/2, (y₁ + y₂)/2 )

 

mid = ( (3 - 5)/2, (4 + 7)/2 )

mid = ( -2/2, 11/2)

mid = ( -1, 11/2)
