the case of linear equations, the graph will always be a line. In contrast, a nonlinear equation may look like a parabola if it is of degree 2, a curvy x-shape if it is of degree 3, or any curvy variation thereof. While linear equations are always straight, nonlinear equations often feature curves.

Answer:
If the graph shows a straight line then it is linear and if it is not straight then its non linear
Step-by-step explanation:
Part a
Every linear graph is nothing more than a straight line so if there is any curves in it, it's not linear. The other way to tell is look at its equation. If the equation can be shaped into Y = MX + B where M and B are numbers, then it's going to be a linear equation.
Part b
For the graphs see the attachments
