Goods             Price elasticity             Cross-price elasticity               Income elasticity

X                           -0.4                                  -0.7                                          -1.8

Y                           -0.9                                  -0.7                                          0.6

Based on the price elasticity, we can say that good X is price elastic. Because price elasticity is always negative for elastic goods.

Based on the cross-price elasticity, we can say that goods X and Y are complements. Because complementary goods have negative cross elasticity.

Based on the income elasticity, we can say that good Y is a normal good. Because normal goods have a positive income elasticity of demand.
