use a coordinate plane to create a rectangular park that has one corner at (-4 1/2, 3 1/2) and a perimeter of 30 units. label the coordinates of each corner of the park. Then plot the points with mixed number coordinates inside the park to represent a swing set, a slide, and a bench. plot the slide farthest from the x axis and the bench closest to the x axis. what are the coordinates of the points you plotted?
