Plotting Points

							Plotting Points

Do you know what the x-
axis and y-axis are?
  The x-axis is the horizontal axis on a grid
  The y-axis is the vertical axis on a grid
                             Also notice
                             where the origin
                             is. This is the
                             point (0,0).
When plotting points the
first coordinate is the x-
coordinate and the second
is the y-coordinate

  (x,y)
Let’s practice by plotting

 When plotting the coordinate (2,4) start at
  the origin and go 2 units to the right and
  4 units up.
What about negative
coordinates?
  Negative x coordinates are to the left of
   the origin and negative y coordinates are
   below the origin.
  Since the x value, 3
   is negative it is
   on the left side of
   the origin.
Any Graphing
Questions?
Let’s practice by playing
