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]
Linear functions
A linear function is a function that has a constant slope/rate, and it is represented by any of the following forms
- Slope intercept form: [tex]y = mx + b[/tex]
- Point slope form: [tex]y - y_1 = m( x - x_1)[/tex]
- General form: [tex]Ax + By= c[/tex].
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
