Answer:
3/4
Step-by-step explanation:
plug values in for x till you get it right
 
        
             
        
        
        
The coordinates of B would be (2, -4)
In order to find this, we need to know that the value of M's points will always be the average of A and B's points. This is because it is the midpoint. Therefore we can use the following formula. 
Value of x
(A + B)/2 = M
(-8 + B)/2 = -3
-8 + B = -6
B = 2
Then we can do the same for the y values
Value of y
(A + B)/2 = M
(-2 + B)/2 = -3
-2 + B = -6
B = 4
 
        
             
        
        
        
 Answer:
(0,-4)
(2,-1)
The first point because it is the y-intercept
second point because it is found our by 3/2 as the slope. slope is rise/run. so you rise three and move to the side 2. as is the point (2,-1)
Hope this helps
 
        
             
        
        
        
I think its the same on both sides so it would be 154 hope this helps and is right have a nice day
