Answer: 272.85
(It’s 21.4 times 12.75)
        
                    
             
        
        
        
Theres a formula to find the midpoint it’s... (x1+x2)/2, (y1+y2)/2. You fill in the x’s and y’s to get (-5+7)/2 for x, which equals 1 and (4-5)/2 to get -0.5. (1, -0.5) is your answer
 
        
        
        
Use substitution 
Given both y values, you know that they have to be equal
3x + 3 = x - 1
2x + 3 = -1
2x = -4, divide by 2
x = -2
Now plug x value into any of the equation to find y value
y = 3(-2) + 3
y = -6 + 3, y = -3
Solution: x = -2, y = -3
        
                    
             
        
        
        
Dividing thirty-two by five we get
x=32/5
 =6•4
