It's both. Look at the gradients between one point then the one after it. It stays constant from one to the next. (Gradient is 2 by the way: (5-3)/(2-1)) 
        
                    
             
        
        
        
Answer:
Z = 8.8 Y = - 42
Step-by-step explanation:
Y = 2 - 5Z
Y = 5 - 47
2 - 5Z = 5 - 47
- 5Z = - 44
5Z = 44
Z = 8.8
Y = 2 - 5 (8.8)
Y = 2 - 44
Y = - 41
Y = 5 - 47
Y = - 42
 
        
             
        
        
        
Answer:
y = -3x - 12
Step-by-step explanation:
Lines that are parallel have the same gradient. 
Therefore using the point (-2,-6) you can make your own equation. 
-6 will be y, -2 will be x
All you have to do is find the y-intercept which is C in <em>y</em><em>=</em><em>mx</em><em>+</em><em>c</em>
-6 = -3(-2) + c
-6 = 6 + c
-12 = c
Therefore;
<u>y = -3x - 12</u>
 
        
             
        
        
        
Subtract 2 numbers then subtract it with 180 (sorry if you get it wrong)
