a) \( A(4,5) B(-3,7) C(-5,-8) \) y \( D(6,-4) \)

Did you know that the coordinates you’ve mentioned represent points in a Cartesian plane? This system was developed by René Descartes in the 17th century and it's super useful for mathematics and physics! For instance, you can calculate the distance between any two points using the distance formula, which makes it easier to visualize and analyze shapes, lines, and much more! If you're planning to work with these points, like forming triangles or quadrilaterals, remember to plot them carefully and check the order! A common mistake is to confuse the coordinates, leading to incorrect shapes or areas. Also, keep an eye on the signs of the coordinates; they indicate their position relative to the origin. Happy plotting!
