What is Linear Transformation?

 A Linear Transformation is a way to change a value or set of values using mathematical rules while keeping the relationship straight (linear), not curved or complex.

It means taking some input values and applying a formula to get output values.

In simple words:

You scale (increase or decrease) or

You shift (move up, down, left, right) the values.


Examples:

If salary is ₹10,000, and you apply a 10 percent increase → New Salary  = ₹11,000

This is linear transformation because you just scaled the value.

If you add 5 bonus marks to student marks:

Original Mark = 70
New Mark = 75

This is also linear transformation.


Zooming an Image without breaking the image structure  is scaling, which is one type of linear transformation.
