Is the function linear, exponential or neither ? Help me please

Hello! :)

$\large\boxed{\text{Linear.}}$

The function pictured is a straight line, so it has a constant slope for all x values.

A function that has the same slope on its domain and when graphed is a straight line is a linear function.
