Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality". video https://cdn.kastatic.org/googleusercontent/QFYWzosaSYGPT31AcLupS8ls6T7KQNlCyZZlbnNc7nmhptP0bZvw7Ul_5N-Hdoy8WOAwoBbWwK7kfbZ_2l89F_o Introduction to proportional relationships Proportional relationships are relationships between two variables where their ratios are equivalent.

If the ratio is always the same, the relationship is proportional. If the ratio changes, the relationship is not proportional. video https://cdn.kastatic.org/googleusercontent/iHIVxAgFvqfpueAIFhNa1Y864prFFIlB0hNoT2b7OdCNbmSwfF54tPTfecOKv1pHiysT93JYfMeM8RAf0VDSd-7D Intro to proportional relationships To know if a relationship is proportional, you should look at the ratios between the two variables.

It's the number we multiply by x to get y. In our example, when x increases, y increases three times as much. So, our constant of proportionality is 3. video https://cdn.kastatic.org/googleusercontent/Oa8jSjyG-T539ycjwPEcyWI7g8QbpxxDLLBzlbNXWa7-pe8Y1yezoNdD5jJlqZaw3z1MNfbr_YC-VT_cX5TvzZFJ Constant of proportionality from graph In this lesson, we learn about the constant of proportionality in a graph.
