Suppose $y = f(x)$ graphed in the figure below represents the cost of manufacturing $x$ kilograms of a chemical.

$f(x)/x$ represents the average cost of producing 1 kilogram of the chemical when $x$ kilograms are made. This problem asks you to visualize these averages graphically.

(a) We can represent $f(8)/8$ as the slope of a line. Through what points does this line extend?
( , ) and ( , )
(Enter your answers as (x,y) coordinates, where the x coordinate in each case is an integer value and the y coordinate is either an integer or the y-value on the curve.)

(b) Complete the inequality:
$f(6)/6$ ? < = > $f(8)/8$
