Given: $y=x-2$ The y-intercept is $-2$, so plot the point $(0, -2)$ where the line crosses the y-axis. The slope is $1$, so plot a second point $(2, 0)$. Draw a line through the two points. The red line represents $y=x-2$. The blue line represents $y=x$. The graph of $y = x-2$ is a graph of $y = x$ shifted 2 units down.
