Which equation is a direct variation function?

y = 4
y = 1/3x+ 4
y = x
y = x3

y=4

Step-by-step explanation:

its asking which one you can answer without any more context, in this case its y=4 because all the other ones evolving x lead to a rabbit hole and will take you in circles.

y=x

Step-by-step explanation:

direct variation form is y = kx where 'k' is the constant of variation

y=4  This has no 'x' variable

y = 1/3x+4  The constant of variation is 1/3 but then 4 is added, so no direct

y = x³  The 'x' variable must be to the power of one

i got 142 as my answer
