Question

Your house is located at (-4,3) which is 4 blocks west and 3 blocks north of the center of town. To get from your house to the mall, you walk 7 blocks east and 4 blocks south. What ordered pair corresponds to the location of the mall?

Answer 1

Since the positive X direction corresponds to the East and the negative Y direction corresponds to the South, then, add 7 to the x-coordinate and substract 4 from the y-coordinate to find the location of the mall:

`(-4,3)\rightarrow(-4+7,3-4)=(3,-1)`

Therefore, the ordered pair that corresponds to the location of the mall, is: (3,-1).
