The solution set is shaded (blue) .

Work Step by Step

Even though there is no x in the relation , we are graphing points in the coordinate PLANE. The line $y=1$ is a border line in the coordinate plane, which divides the plane into two regions, One region will have coordinates (x,y) such that $y > 1,$ in the other, $y < 1$, points on the border will have y=1. 1. The inequality sign is $ 1\quad ?$ No, the region that (0,0) belongs to is not the solution set. 3. Shade the region that (0,0) does not belong to. This is our solution set.
