Direct and Inverse Proportions Class 8 Maths Notes – Chapter 13

When two variables change in the same sense i.e as one amount increases, the other amount also increases at the same rate it is called direct proportionality. When two variables such as x and y are given, y is directly proportional to x if there is non zero constant k. The constant ratio is called constant of proportionality or proportionality constant.
