Vincenzo plotted point K in the coordinate plane below. On a coordinate plane, point K is 0.5 units to the right and 0.5 units down. He says that the plotted point is (Negative one-half, one-half). What is Vincenzo’s error? The x- and y-coordinates are switched. Both coordinates should be positive. The x-coordinate should be One-fourth. The y-coordinate should be One-fourth.
