You move left 4 units and up 1 unit. You end at (3, 4). Where did you start?

Answer 1

Hi Angela,

You can approach this problem by thinking about going in the opposite of the directions indicated starting at the point (3, 4).

If you ended at an x-coordinate of 3 after having moved 4 to the left, then you can start at 3 and move 4 to the right to see what x -coordinate you started at: 3 + 4 = 7

The x coordinate of the STARTING point would have been 7.

You can do the same with the y-coordinate: start at 4 and travel down 1 unit. The y-coordinate of the STARTING point would be 3.

Therefore, the coordinates of the starting point would have been (7,3)
