Answer:
15.7 inches
Step-by-step explanation:
A clock is a circle .  It tells us that the radius of the circle is 2.5 inches, and it is asking for the circumference.  Therefore, we can use the equations for a circle to solve for the circumference.

 
        
             
        
        
        
The slope-intercept form: y = mx + b
m - a slope
b - y-intercept (0; b)
-y + 8x = 2x      |subtract 8x from both sides
-y = -6x      |change signs
y = 6x
Answer: The slope m = 6, y-intercept b = 0 -> (0; 0).
