Answer: Choice D
Explanation:
When we think of proportional relationships, we can think of ratios. The x and y value will be multiplied by the same ratio throughout the table to create equivalent points. The easiest way to do this is to turn the points into fractions and see if they all simplify to the first point, which in this case is 2/3.
4/6 / 2/2 = 2/3
6/9 / 3/3 = 2/3
8/12 / 4/4 = 2/3
2 is being added to the x value each time and 3 is being added to the y value each time. hope this helps!
