In your day to day, is there any occurring fact that can be interpreted as linear systems and non-linear systems?

Step-by-step explanation:

Linear relations are those which are represented by straight line on a graph i. e. increase or decrease a variable directly effect the other in a linear way

for example

y=2x+3

increase in value of x increase the value of y linearly.

Non-linear relationship are those in which change in one entity does not correspond to change in other quantity.

Real life situation for linear relation is when we apply force on a block it accelerates and it goes on increasing as force is increasing.

For Non-linear relation

increase in temperature vs time spend

Time spent is more to increase the slight amount of temperature.
