Question

Tell whether the equation represents a direct variation. If so, identify the constant of variation.
y = 3x

accessdenied · Answer

A 'direct variation' is some equation in the form:
  y=kx

That certainly looks like an equation that meets this requirement.  The constant of variation is 3 (the k value in y=kx).

how would i do this?

"Tell whether the equation represents a direct variation."
  So, the question is answered with yes/no.
     y = kx
     y = 3x
  The answer would be yes, this is a direct variation.

"identify the constant of variation."
  The constant of variation is the coefficient on x in the equation when we know it is a direct variation.  The constant of variation is 3.
