Answer:
-1
Step-by-step explanation:
We can find the slope by change in y of change in x
change in y
---------------------
change in x
The y changes  -3  ( goes down 3)
the x changes +3 ( to the right 3)
-3
----
3
This simplifies to -1

Answer:19
Step-by-step explanation:
90 - 23 = 67, 67 = 4x - 9, 76 = 4x, 76 / 4 = 19
 
        
                    
             
        
        
        
Let y=x+6 be equation 1...
Replace equation 1 in equation 2
X+6 =-2x-3 
X+2x = -3 -6
3x = -9
X = -3
