A marker starts at the origin of a four-quadrant grid and has to be moved to the point (-5, 2). Which movement takes it there?

  1. 2 units left, then 5 units up
  2. 5 units down, then 2 units right
  3. 5 units left, then 2 units upՃիշտ պատասխան
  4. 5 units right, then 2 units down

Բացատրություն

The x-coordinate is read first, so five below zero means five units to the left, and a y-coordinate of two means two units up. Moving two units left and five units up uses the same numbers in the reverse roles and lands the marker somewhere else entirely.
