Question

What is direct and inverse proportion

Answer 1

Direct proportion means as the independent variable increases, the dependent variable increases, vice versa
Inverse proportion means just the opposite. As the independent variable increases, the dependent variable decreases, and vice versa.

Answer 2

direct proportionn means when x increases,y increases, when x decrease, y decrease

indirect is oposite, when x increase, y decrease, when x decrease, y increase

if you said
y is directly proportional to x that is
y/x=k
or y=kx

y is inversly proportional to x then that is
yx=k
or y=k/x
