Step-by-step explanation:
m1.m2 = -1
18.m2 = -1
m2 = -1/18
formula = y - y1 = m2 ( x - x1)
y - (-5) = -1/18 ( x -1)
y + 5= -1x/18 +1/18
y = -1x/18 -89/18
 
        
             
        
        
        
The expression for the perimeter would be
2(x) + 2(2x+7)
which can be simplified to 2x+4x+14 
which equals 6x+14
        
                    
             
        
        
        
Answer:
The lengths of time that his mom reads are typically longer and have more variability than the lengths of time that his dad reads.
Step-by-step explanation:
The Mom's plot is longer in ranges, therefore, she would have more variability than the dad.
