Generally when we say x is proportional to y, we think that when x increases y increases. Now I am questioning whether that is actually true. If k is negative, then when x increases, y DECREASES. My question is does this mean this statement is incorrect: If x is proportional to y, when x increases, y increases proportionally. Is it more correct to say: If x is proportional to y, when x increases, y either increases proportionally or decreases proportionally. Along the same line of reasoning, when x is inversely proportional to y, we think that when x increases y decreases, but that is true only if k is positive. Is that correct?Answered by Harley Weston.
