I don't understand or see for the matter the question what is it 
        
             
        
        
        
X by its self is always 1x
1x+8=-15 you have to get rid of 8 by subtracting on both sides 
1x=-23 now get rid of 1 by dividing on both sides 
x=-23
        
             
        
        
        
Answer:
0.324
0.068
Step-by-step explanation:
If Russell is 5'9" ; then he is under 6 feets : 
Probability = number of forwards under 6 feets / tot number of players 
Probability = 120 / 370 = 0.324
Peter is 6'2" ; Peter is over 6 feets ;
Probability that Peter is a guard = (number of guards over 6 feets / total number of players) = 25 / 370 = 0.0676 = 0.068
 
        
             
        
        
        
The slope is the change in Y over the change in X:
Slope = (3 -12) / (4-0)
Slope = -9/4
The answer is the 3rd choice.
