Neither of them are correct. When you plug in both of the fractions into the equation, you get answers like 2/9 (from plugging in 1/3) and 1/9 (from plugging in 1/6). None of them are equal to 9.
This isn't math.

Answer:
centre = (
, 1 )
Step-by-step explanation:
using the midpoint formula
midpoint = [
(- 1 + 4), (5 - 3) ] = (, 1 )
So the equations are:
y= 3x + 3
y= x- 1
By the transitive property, we know x-1= 3x+3 (Transitive property means if a= b, and b= c, shouldn't a = c if they both equal b?)
so, x- 1= 3x + 3. Now we isolate x and solve:
+1 +1
x= 3x+ 4
-x -x
0 = 2x+ 4
-4 -4
-4 = 2x
/2 /2
x= -2
Now, you can plug that back in to find y:
y = x- 1
y= -2 -1
y= -3
Then plug them both in to make sure it is correct. :o)
