A. 7/4 
Rate of change is the same as slope, it is how the line has to go to get from the first to the second point. The slope function is y2-y1 / x2-x1. So we end up with 8-1/5-1 making 7/4
        
             
        
        
        
The solution to 6×+2y=6 is y=0.5
The solution for 7×+3y=5 is y
=  0.238095 (.238095 is repeated)

Answer:
D = 0 , Dx = 4 , Dy = -6 , Dz = 2 
Step-by-step explanation:
As per<u> cramer's rule</u>, 
D = |   7    6    4  |  = 0 
       |   3    3    3  |
       |   4    4    4  |
Dx =  |  10    6    4  | = 4 
         |   1    3    3    |
         |   2    4    4   |
Dy = |   7    10    4  | = -6 
        |   3    1     3   |
        |   4    2    4   |
Dz =  |  7    6    10 | = 2 
         |   3    3    1   |
         |   4    4    2  |
