HOY = Horizontal line, m=0, y is the only variable in the equation
VUX = Vertical line, m= undefined, x is the only variable in the equation
        
                    
             
        
        
        
Answer:
87
Step-by-step explanation:
Because in that set of data 85 and 89 are in the middle so you have to find the number between 85 and 89 and it is 87
 
        
                    
             
        
        
        
First find the slope of the line connecting these two points:
 6-5
m = ------------ = -1/2
 -4+2
Substitute this slope into y = mx + b: y = (-1/2)x + b.
Next, subst. 5 for y and -2 for x, and find b:
5 = (-1/2)(-2) + b, or 5-1=b. Then b = 4, and
the equation of the line is y = (-1/2)x + 4.
