If they are proportional, then y/x should always be the same. 
So 9/2= 4.5
We need to find the y value at x=3 to make y/x equal 4.5
4.5 = y/3
y = 4.5*3 = 13.5
        
             
        
        
        
Answer:
The 10th term is 50
Step-by-step explanation:
5(10) = 50
 
        
             
        
        
        
The solution to the problem is 16.
first, you must set up the equation.

Then, simplify exponents.
256*
Next, simplify the equation.
16
 
        
             
        
        
        
we know that
the fourth point is plotted 5 units to the right of (-4,4)
so
the coordinate x of the fourth point is equal to
-4+5=1
the y-coordinate of the fourth point is the same y coordinate of (-4,4)
therefore
the coordinates of the fourth point is (1,4)
