See below:

Explanation:

Let's think about what the equation #y=x# means:

On a standard #xy# plane, if #y# is equal to #x#, then the coordinates would be the same.

Some of the points on the graph #y=x# will be #(3,3), (5,5) and (7,7)#.

Since the coordinates are the same, the graph will just be a line with slope #1# extending out from the origin #(0,0)#. Both #x# and #y# will be the same.

Hope this helps!
