Answer» Answer: Hi! Because the sides of the rectangles are parallel to the x and y axes, the VERTICES given PROVIDE BOUNDARIES that are parallel to the axes. So, with the point (6,2), you know that the RECTANGLE is bounded by x=6 and y=2, respectively. Similarly, the other point, (3, 4) provides two additional boundaries: x=3, and y=4 The intersections of x and y boundaries provide the vertices - you know, already, that x=3 and y =4 intersect at (3,4) and that x=6 and y=2 intersect at (6,2) - the other vertices exist where x=3 and y =2 intersect AND where x=6 and y=4 intersect- namely (3,2) and (6,4)… |
