How do you graph the equation #y=x#?

#y=x# is an equation. And just like any equation, if we set #x# equal to something, we can solve for #y#.

Let's se #x=0#. That means #y=0#. So our first coordinate pair is #(0,0)#.

Now let's use a different number, say, #10#. #x=10#, so #y=10#. Thus, the coordinate is #(10, 10)#.

I'm noticing a pattern here. #x# and #y# have the same value. If we graph the equation, it should be an even, positive line. We know it passes through #(0, 0)#, and then we can make the slope #1#.

Our graph should look like this graph{y=x}
