Does the equation #3x - 6y = 0# represent a direct variation and if so, identify the constant of variation?

Answer 1

Eva Abramson

Yes , Constant of variation is #2#

# 3x -6y =0 or 3x = 6y or x/y= 2 or x = 2*y :. x prop y #

# x =k*y :. k=2 # , k= constant of variation.

Yes , Constant of variation is #2# [Ans]

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
