Question

Difference between Direct Proportion and Inverse Proportion.

Answer 1

Difference between Direct Proportion and Inverse Proportion:

Criteria	Direct Proportion	Inverse Proportion
Definition	A relationship where two variables increase or decrease together, maintaining a constant ratio	A relationship between two variables when one increases and the other decreases and vice versa, such that the product of their corresponding values remains constant
Symbol	y ∝ x	y ∝ 1/x
Formula	y = kx y is the dependent variable. x is the independent variable. k is the constant of proportionality. x and y vary directly.	y = k/x x and y are two variables. k is the constant of proportionality. x and y vary inversely.
Graph	It is a straight line.	It is a hyperbolic curve.
Examples	As speed increases, the distance covered increases and vice versa.	The number of workers for work and the amount of time for work completion. More the workers, the less time is taken for completion of the work and vice versa.
