Write an equation for the transformation of Y equals X

The equation for the transformation of y = x can be written as:

f(x) = bx + a

Where:
- "f(x)" represents the transformed y value.
- "b" represents the scaling factor, determining the slope of the line.
- "a" represents the constant shifting or translation of the line along the y-axis.

Therefore, the transformation equation for y = x is f(x) = bx + a.
