The commonly known fact is that if you have a line ax + by = c, then a perpendicular line is -bx + ay = d (where "a", "b", "c" and "d" are constant values). Using it, we see that in our case an equation of the desired line is -2x + 3y = d (where d is some constant). And since this line should pass through (0,0), d = 0. Thus, the desired equation is 3y = 2x, or, in the form y = ax+b, it is y =. ANSWER
