Which explains whether or not the values in the table represent a direct variation? x 4 6 10 20 y 1 1 point 5 2 point 5 5

For a direct variation, the ratio y/x must be constant for every pair of values. Here, 1/4 = 1.5/6 = 2.5/10 = 5/20 = 0.25. The values are proportional, so the table represents a direct variation.
