The linear functions are [tex]y = -2x[/tex] and [tex]3x - 4y = 12[/tex], while the non-linear function is [tex]y =z^2 + 11[/tex]
A linear function is a function that has a constant slope/rate, and it is represented by any of the following forms
Other functions that do not take any of the above forms are non-linear functions.
So, we can conclude that:
[tex]y = -2x[/tex] and [tex]3x - 4y = 12[/tex] are linear functions, while [tex]y =z^2 + 11[/tex] is a non-linear function
