Answer:
Opposite angles in a parrellelogram are 
congruent. 
 
        
                    
             
        
        
        
2p-b=c-ap 
2p+ap=c+b
p(2+a)=c+b
So, p=(c+b)/(2+a)
        
                    
             
        
        
        
Answer:
y= 3/5x+ 6.2
Step-by-step explanation:
the slope is change in y over change in x. 
-4-(-1) divided by 3-8 will be -3/-5 = 3/5
For the y-intercept, plug in x and y values. I will use (3,8). 
8= 3/5(3)+b
8= 9/5+b
(subtract 9/5 from both sides)= 6 and 1/5 or 6.2 as a decimal.
