Without graphing, it is difficult to determine the line of symmetry for an arbitrary shape. However, the given image appears to be a square with one vertex at the origin and sides of length 8 units. Since a square has four lines of symmetry, it is unclear which line of symmetry the question is asking for. However, by inspecting the shape, we can see that it is centered at the point (0,0) and thus the line of symmetry must pass through this point. The only answer choice that satisfies this condition is C, x=1, which is a vertical line passing through the point (1,0).
