To solve this you have to add 98 and 82 together then divide by three so the answer would be 60
        
                    
             
        
        
        
The answer to the question
 
        
        
        
Answer:
3.4545
Step-by-step explanation:
 
        
             
        
        
        
Y=mx+b b is the y intercept which is 4
m is the slope which is rise over run which is -4/2 which is -2 
Linear y=-2x+4
        
             
        
        
        
For the first question you just need to add up all the sides. so first add all the x numbers and then add all the plain numbers.
a perimeter is the total length around the shape.
