Answer:
slope = 
Step-by-step explanation:
calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (9, 6 ) and (x₂, y₂ ) = (4, 5 )
m =  =
 =  =
 = 
 
        
             
        
        
        
9.286 
[To change to mixed number, count the number of digits after the decimal point. There are 3 digits, so the denominator will be 1000]

Then we simplify the fraction
(286 ÷ 2)/(1000÷2) = 143/500
Therefore,
