Step-by-step explanation:
We know,
'Direct Variation function' is the function where two quantities vary directly i.e. variables x and y are said to be directly varying if 'y=kx' where k is the constant of variation.
Thus, from the options, we see that the function,
is varying directly with the constant of variation i.e. k = 1.
is also varying directly with constant
