Plot these points on the axes, and join them up dot-to-dot fashion in the order in which they are plotted:
(0,0) (-3,5) (-2,7) (0,0) (-6,1) (-5,3) (0,0) (6,-1) (5,-3) (0,0) (3,-5) (2,-7) (0,0) (-2,-7) (-3,-5) (0,0) (-5,-3) (-6,-1) (0,0) (6,1) (5,3) (0,0) (3,5) (2,7) (0,0)
Plot these points, and again join them up in the order in which they are given:
(2,0) (2,-2) (4,-2) (4,-4) (6,-4) (6,-6) (8,-6) (8,-8) (6,-8) (6,-6) (4,-6) (4,-4) (2,-4) (2,-2) (0,-2) (-2,-2) (-2,-4) (-4,-4) (-4,-6) (-6,-6) (-6,-8) (-8,-8) (-8,-6) (-6,-6) (-6,-4) (-4,-4) (-4,-2) (-2,-2) (-2,0)
Now complete the pattern by reflecting everything, using the x-axis as the mirror line...
What sort of design will you get if you plot these points and join them up in order?
(0,0) (-2,0) (-2,2) (0,2) (2,2) (2,-2) (-4,-2) (-4,4) (4,4) (4,-4) (-6,-4) (-6,6) (6,6)
