Turn them all into decimals so you can clearly see the difference between them
8 1/9 = 8.11
8.117
8.28
163/20 = 8.15
8 1/9, 8.117, 163/20, 8.28 is your answer
        
             
        
        
        
-4-(2m+3)=-m-(5+3)
-4-2m-3=-m-5-3m
-2m-7=-4m-5
-2m+4m=-5+7
2m=2
m=2/2
m=1
        
             
        
        
        
Answer: the x-intercept is (-10,0), the y-intercept is (0,45/2)
Explanation: 
First, we need to determine the function describing the line. 
From the table, it is obvious that the y values increase by 9 every increase of 4 of the x values. So, the slope is 9/4 and the function looks like this:

with the y-intercept (or bias) b still unknown. This can be determined by using one of the point from the table, like so:

The above function form makes it easy to read off the y-intercept, which is (0,45/2) or (0,22.5). The x-intercept is obtained by setting y = 0 and solving for x:

The x-intercept is (-10,0)

Pulling out like terms
 4.1     Pull out like factors :
   -12n - 48  =   -12 • (n + 4) 
Equation at the end of step

:
  -12 • (n + 4)  = 0

Equations which are never true:
 5.1      Solve :    -12   =  0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
 5.2      Solve  :    n+4 = 0 
 Subtract  4  from both sides of the equation : 
                      n = -4
One solution was found :
 n = -4
