The answer is the second option.
Step-by-step explanation:
y-7/4-7=x+8/8-8
-y+7/3=0
y=7
((X1+x2)/2,(y1+y2)/2)
---> ((2+2)/2,(1+4)/2)
---> (2,2.5)

Answer:
9. c. 1
10. c. y = 15/x
Step-by-step explanation:
The equation for inverse variation can be written as ...
y = k/x
The value of k can be determined from given values of x and y. Multiply by x to get ...
k = xy
Solving for x, you get ...
x = k/y
___
9. k = (1/7)(49) = 7
x = k/y = 7/7
x = 1
__
10. k = (3)(5) = 15
y = 15/x
