The coordinates (3, - 1) (1, - 3) and (5, - 3) were plotted to draw a triangle on a coordinate plane. Is the polygon in Quadrant I, II, III, or IV? Answer 1 for Quadrant I, 2 for Quadrant II, 3 for Quadrant III, or 4 for Quadrant IV. (1 point)

The polygon is in Quadrant I because all the points have positive x and y coordinates. Therefore, the answer is 1.
