**Weegy:** Midpoint is (11+5/2,6+8/2).Hence (8,7)

**User:** What is the center of the circle that has a diameter whose endpoints are (6, -4) and (18, 10)?

**Weegy:** (12, 6)

**User:** What is the center of the circle that has a diameter whose endpoints are (-3, -5) and (-11, -7)?

**Weegy:** The slope of the line passing through the points (-4, -5) and (-8, 6) is m= -11/4.

**User:** Find the midpoint of the line segment whose endpoints are (2.6, 5.1) and (3, 4.7).

**Weegy:** ?1.5 is the coordinate of the midpoint of a segment with the endpoints at ?9 and 6.

**User:** What is the abscissa of the midpoint of the line segment whose endpoints are (5, 2) and (, 2)?

**Weegy:** ((5v2+v2)/2, (2v3+2v3)/2)
= (6v2/2, 4v3/2)
= (3v2, 2v3)
Abscissa (x-coordinate) = 3v2
Ordinate (y-coordinate) = 2v3
Answer: 2. 3v2

Let (x,y) be the other endpoint of diameter. [ Then (4,6) is midpoint of (x,y) and (2,5)
((x+2)/2, (y+5)/2) = (4,6)
(x+2)/2 = 4
x + 2 = 8
x = 6
(y+5)/2 = 6
y + 5 = 12
y = 7
Other endpoint is (6, 7)

(More)The midpoint of the line segment whose endpoints are (7, 5) and (7, 11) is ( 7 , 8 ) .

Let the midpoint is ( x ,y )

x = ( 7 + 7 ) / 2 =7

y = ( 5 + 11) / 2 = 8

The center of the circle that has a diameter whose endpoints are (6, -4) and (18, 10) is ( 12 , 3 ) .

Let the center is ( x , y )

x = ( 6 + 18 ) / 2 = 12

y = ( - 4 + 10 ) / 2 = 3

The center of the circle that has a diameter whose endpoints are (-3, -5) and (-11, -7) is ( - 7 ,- 6 ).

Let the center is ( x , y )

x = ( - 3 - 11) / 2 = - 7

y = ( - 5 - 7 ) / 2 = - 6

The midpoint of the line segment whose endpoints are (2.6, 5.1) and (3, 4.7) is ( 2.8 , 4.9 ) .

Let midpoint is ( x , y )

x = ( 2.6 + 3 ) / 2 = 2.8

y = ( 5.1 + 4.7 ) / 2 = 4.9
