Direct proportion: We can say two quantities x and y in direct proportion if they increase (decrease) together in the same manner. Two measurable quantities are said to be directly proportional if the increase in one quantity results in the increase of the other quantity and vice versa. However, you will be expected to know how to work with constants of proportionality and use these equation, so all of this content is still important to you. Students will also learn to identify if the coordinates on a graph share a proportional relationship. Play. 3.
