Is #3x-6y=0# a direct variation? Algebra Graphs of Linear Equations and Functions Direct Variation 1 Answer GiĆ³ Apr 7, 2015 Yes. Every time #x# increases of one unit #y# increases of a fixed amount equal to #1/2#. If you separate #y# on one side and #x# on the other you'll find: #6y=3x# and: #y=3/6x# or #y=1/2x# Answer link Related questions What is Direct Variation?
