Anthony was asked to give the coordinates of a point located in quadrant III. He gave the ordered pair (4, –10). Which statement best describes the error that Anthony made?

In quadrant III, both coordinates must be negative: x < 0 and y < 0. Anthony’s point (4, –10) has a positive x-coordinate and a negative y-coordinate. Therefore, his x-coordinate has the wrong sign; the correct choice is “His x-coordinate is the wrong sign.”
