A direct variation suggest that the value of x in the equation would greatly affect the value of y such that when x is increasing, y also increases and the other way around. The equation for a direct variation is that,
                               y  = kx
Substituting the given values in the ordered pair,
                           5 = k(4)   ; k = 5/4
