Adirect variation function includes the ordered pair (4, 5). which statement is true? the constant of variation k is mc001-1.jpg. the constant of variation k is mc001-2.jpg. it is not possible to determine the constant of variation from the information given.

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

(-0, -7) is your answer
