examining the ratios of the corresponding values in the relationship. If the ratios of the values remain constant, then it is a direct variation. In other words, if the ratio of y-values to x-values stays the same for all points in the relationship, then it is a direct variation. Another way to determine if a relationship is a direct variation is by graphing the data points. If the resulting graph is a straight line passing through the origin (0, 0), then it is a direct variation. Direct variations have the form y = kx, where k is the constant of variation.

Certainly! To determine if a relationship is a direct variation, you can:

1. Check if the ratios of the corresponding values in the relationship are constant.
2. Graph the data points and see if they form a straight line passing through the origin.

If the ratios of the values remain constant or the graph is a straight line passing through the origin, then it is a direct variation. Direct variations follow the form y = kx, where k is a constant.
