60 because 2:4 is 1/2, and when you divide by a fraction, you multiply by the reciprocal (2/1 instead of 1/2) which would be 60 in this case.
        
             
        
        
        
Answer:
(1.5, -6)
Step-by-step explanation:
To find the x coordinate of the midpoint
(x1+x2)/2 = (8+-5)/2 = 3/2 = 1.5
To find the y coordinate of the midpoint
(y1+y2)/2 = (-3+-9)/2 = -12/2 = -6

The f(x) notation means that were ever you see n x on the right you put the value of x.  
The question is which point has x = - 3 and what is the associated y value?
You could do it this way, just so you understand it.
<h2>X                        Y</h2>
=========================
-3                                      2       <======
-1                                       0
1                                         1
3                                        -3
The answer must be the first one
