Suppose X and Y are two variables in a model. For each of the relationships described below, check the box if the relationship can be expressed as a linear equation or inequality. It would help to write down the relationship algebraically. The sum X + Y is twice the difference X - Y The ratio X/Y must not exceed 2Y. X grows as the square of Y. The sum of the reciprocals 1/X and 1/Y is equal to 2. The product of X and Y must be no more than 3. The sum of X and one-third Y must equal 5. The ratio of X to Y must be at least 1.5. The proportion of X in the total X + Y cannot exceed 10. X is inversely proportional to Y X grows 2.5 times as fast as Y.
