Answer:
400 - 120 - 220 -175 -60 +50 = -125
Step-by-step explanation:
 
        
             
        
        
        
Let the temperature at 10am be x, then
x + 8 = 56
x = 56 - 8 = 48 degrees F
Let y be the temperature at 8am, then
y - 2 = 48
y = 48 + 2 = 50 degrees.

Answer:
   see the attachment
Step-by-step explanation:
The x- and y-intercepts are easily found:
<u><em>X-intercept</em></u>
Set y = 0 and divide by the coefficient of x.
   -x +0 = 8
   x = -8
__
<u><em>Y-intercept</em></u>
Set x = 0 and divide by the coefficient of y.
   0 -2y = 8
   y = -4
__
Now, we have two points on the graph: (-8, 0) and (0, -4). A third point can be one that is halfway between these: (-4, -2). The graph is attached.
 
        
             
        
        
        
For my answer i got y = x - 18
