Work Step by Step
Consider the provided equation,
$y=x$
Now, choose some values for $x$ and compute the value for $y=x$, in order to form the ordered pairs to plot on the graph.
So, put $x=-3$ in the provided equation $y=x$,
$y=-3$
Put $x=-2$ in the provided equation $y=x$,
$y=-2$
Put $x=-1$ in the provided equation $y=x$,
$y=-1$
Now, put $x=0$ in the provided equation $y=x$,
$y=0$
Now, put $x=1$ in the provided equation $y=x$,
$y=1$
Put $x=2$ in the provided equation $y=x$,
$y=2$
Put $x=3$ in the provided equation $y=x$,
$y=3$
