Describe the shape of the graph f(x)=x

The shape of the graph of f(x)=x is that of a linear function.

Step-by-step explanation:

The graph f(x)=x is the parent function of the linear function.  It is a positive function since it goes upward from left to right, and it passes through the point of (0,0).  It also has a slope of 1, which is the slope of the parent function, or the graph of f(x)=x.  Note once again: The parent linear function and the graph of f(x)=x are the exact same graph.
