# How can I shade an region of a graph using the graph function?

##### 1 Answer

Let's say I have the inequality

graph{x}

To work with shading and multiple graphs, you need to change the format of what is graphed - essentially we add

graph{y-x=0}

To shade, change the equal sign to an inequality. "graph { y-x>0 } " gives:

graph{y-x>0}

There are a number of existing answers that give more advanced tips on limiting graphs and shading, creating shaded shapes, and more. Here are a few:
