Answer:
The point on the line is not filled in (so just a white circle) because the sign is an "equal to" sign. The line always faces the opposite side of the jaws, so in the case of x > 4, the line goes right starting from the hollow point above 4.
 
        
             
        
        
        
Here is the answer and the solution:
Let P= error
n = number of operations
P = .016
n = 250
Multiply P and n
.016 (250) = 4
The number of times it may fail is 4.
        
                    
             
        
        
        
Answer:
Well, since there are four options, and Jamal is likely to pick any of them, 25% is the answer. 25 is also 1/4.

500,000
(5 or above, give it a shove)
 
        
                    
             
        
        
        
To find slope: 
(y1 - y2) / (x1 - x2)
(0-3)/(-4-0)
Slope is 3/4
So the equation is 
y=3/4x + 3
