Answer:
C
Step-by-step explanation:
To be a factor of 16 they need to be numbers that divide into it without remainders.
 
        
             
        
        
        
(1,11/4)(2,25/4)
slope = (25/4 - 11/4) / (2 - 1) = (14/4) / 1 = 14/4 = 7/2
y = mx + b
slope(m) = 7/2
(1,11/4)...x = 1 and y = 11/4
now we sub and find b, the y int
11/4 = 7/2(1) + b
11/4 = 7/2 + b
11/4 - 7/2 = b
11/4 - 14/4 = b
-3/4 = b
so ur equation is : y = 7/2x - 3/4
        
             
        
        
        
I'd suggest using "elimination by addition and subtraction" here, altho' there are other approaches (such as matrices, substitution, etc.).
Note that if you add the 3rd equation to the second, the x terms cancel out, and you are left with the system
 - y + 3z = -2
   y  + z  =  -2
-----------------
         4z = -4, so z = -1.
Next, multiply the 3rd equation by 2:  You'll get -2x + 2y + 2z = -2.
Add this result to the first equation.  The 2x terms will cancel, leaving you with the system
2y + 2z = -2
  y  +  z  = 4
This would be a good time to subst. -1 for z.  We then get:
-2y - 2 = -2.  Then y must be 0.  y = 0.
Now subst. -1 for z and 0 for y in any of the original equations.
For example, x - (-1) + 3(0) = -2, so x + 1 = -2, or x = -3.
Then a tentative solution is     (-3, -1, 0).
It's very important that you ensure that this satisfies all 3 of the originale quations.
