Answer:
slope = 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 8) and (x₂, y₂ ) = (- 4, 0)
m =  =
 =  = 2
 = 2
 
        
                    
             
        
        
        
Answer:
755s
Step-by-step explanation:
60*12+35=755
This is the way
 
        
                    
             
        
        
        
Find the common denominators. for the miles 5 and 3 go into 15. so 2/5 times 3 is 6/15. and 2/3 times 5 is 10/15. for the hours 5 and 9 go into 45. 1/5 times 9 is 9/45. and 2/9 times 5 is 10/45. so Susan ran 6/15 of a mile in 9/45 of an hour. and Kim ran 10/15 of a mile in 10/45 of an hour. 
so Kim ran 3 miles in an hour. Susan ran 2 miles in an hour.
        
             
        
        
        
The first answer is figure B
the second is figure A because all angles are equal
the third is Hex regular
the 4th is octagon not regular
the 5th is hex regular 
merry christmas my apologize for being to vague with my last answer
