The two quantities, the score on a test and the number of incorrect answers on the test, do not vary directly.
In direct variation, as one quantity increases, the other also increases proportionally. However, in this case, as the number of incorrect answers on the test increases, the score on the test decreases.
Therefore, there is an inverse relationship between the score and the number of incorrect answers. As one quantity increases, the other decreases. This indicates that the two quantities do not vary directly.
Tell whether the two quantities vary directly. Explain your reasoning.
