Plotting with Negative Coordinates - Visualizing Algebra

  • 0:00 - 0:04
    >> Well, this ordered pair, or point would be here. If you got this right, well
  • 0:04 - 0:09
    done. I haven't even told you about negative coordinates yet. To think about a
  • 0:09 - 0:13
    negative coordinate, instead of moving right, we want to move left. We move left
  • 0:13 - 0:18
    because it's the x coordinate. We move in the horizontal direction, this way. So
  • 0:18 - 0:22
    from the origin, we move three units left and then two units up. I know it can't
  • 0:22 - 0:27
    be either of these points because well the x coordinate would be positive and
  • 0:27 - 0:32
    ours is negative, so these are out. The same would be true for this coordinate,
  • 0:32 - 0:36
    the x value would be positive 3. If you chose this point, you were a close
  • 0:36 - 0:41
    second. This point is really 3 to the left or negative 3. And then down 2, so
  • 0:41 - 0:45
    negative 2 in the y direction. But we don't have a negative 2, we have a
  • 0:45 - 0:51
    positive 2 for our y coordinate. Once we move three units to the left of the
  • 0:51 - 0:54
    origin, we must move two units up. So one, two.
