Linda is searching for her friends house. From hotel, she walked 3 blocks east and 9 blocks north. Then she walked 5 blocks west and 2 blocks north to find her friends house. How many blocks from her hotel is she now? Represent the translation in vector notation. (North is represented in the positive direction of y-axis.)
