In directly proportional the two variable vary in the same "direction". So, if one increases, the other increases.

In inversely proportional, the two variable vary in opposite "directions". So, if one increases, the other decreases.

Two variables, X and Y, are directly proportional if Y = cX where c is a constant. They are inversely proportional is Y = k/X where k is a constant.

Force is directly proportional to mass provided the acceleration is constant.


How do you tell if a math table is inversely proportional or directly proportional?

Generally, if y increases as x increases, this is a hint that the quantity is directly proportional, and if y decreases as x increases, the relation might be inversely proportional. However, this is not always the case. x and y are directly proportional if y = kx, where k is a constant. x and y are inversely proportional if y = k/x, k is constant. This is the best way to tell whether the quantities are directly or inversely proportional.


How can you tell the difference between a graph in which one variable is directly proportional to another and a graph in which two variables vary inversely?

1. You can tell the difference because the proportional one has the same slope while the inversely one has opposite reciprocal slope.
