find the slope of all 18 line segments above.
The inner triangle that makes the eye has three points on it: ( , ) ( , ) & ( , )
The slope of line 1 is :
The slope of line 2 is:
The slope of line 3 is:
On the dragon's head, line segment 4 is between points ( , ) and ( , ). I can use counting OR the slope formula (which is... )
Using that same process for lines 5-18, the slopes are
