    standard form does not like a minus sign on the x value. That rules out two of your choices. (standard form puts the variables in alphabetical order, so first x then y) I would multiply your original equation by 3: every term on both sides of the = that should get you started.

    3 times (-2/3x) = (3/1) times (-2/3x) 3 times (-2/3x) = (3*-2)/(1*3)x 3 times (-2/3x) = (-6)/(3)x 3 times (-2/3x) = -2x
