Answer:
<em>( - 15, - 16 ) </em>
Step-by-step explanation:
Coordinates of midpoint are (
,
)
( - 5 + x ) / 2 = - 10 ⇒ x = - 15
( 4 + y ) / 2 = - 6 ⇒ y = - 16
<em>( - 15, - 16 )</em>
1) 4x+6= 10; x=1
2) c + 5= 15; c=10
3) 2 - a= 18; a= -16
4) -8x=16; x= -2
5) a+6= 12; a=6
6) 3+b= 18; b=6
7) -5 - x= 19; x= -24
8) 7+4b= 34; b= 6.75
