The quotient of F and the product of r, s, and T

Behold the quotient of F and the product of r,s, and T:  F / (r·s·T)

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
