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 answer

The points (3, -1), (1, -3), and (5, -3) all have negative y-coordinates, which means they are all below the x-axis. Therefore, the triangle formed by these points is in Quadrant III.

Therefore, the answer is 3 for Quadrant III.
