RECALL The graph of $y=k, k\ne0$ is a horizontal line whose y-intercept is $(0, k)$. All points on this line have a y-coordinate of $k$. Thus, the line $y=6$ is horizontal with a y-intercept of $(0, 6)$. Since all points on this line have a y-coordinate of $6$, then the following points are on the line: $(-2, 6)$, $(0, 6)$, and $(2, 6)$ Plot these three points then connect them using a line. (Refer to the answer part above for the graph.)
