Jackson is at his house, which is located at (4,-10) on a coordinate plane. He needs to go to the grocery store, which is located at (-21,-3). One unit on the coordinate plane represents 1 block, and north is in the positive y direction. Jackson travels 13 blocks from his house to the store. Draw one possible route for Jackson on the coordinate plane. He can only travel on the grid lines. Show the calculations that prove your route is 13 blocks long.
