12. The ordered pairs
The red colors on previous slide are the points on the
parabola.
The ordered pairs are found on the vertex of the
squares, upper vertex of squares 1,3,4 and 6.
The lower portion which is the origin is found on the
sides of squares 3 and 4.
13. Sample 2: y2 =8x
In this case the graph has an
axis of symmetry which is the
x- axis , and the directrix is at
the left side of the origin
15. The squares
Length of latus rectum
directrix
Vertex (0,0)
The red colored are the points
on the parabola that passes the
edges of the squares
All the
squares have
the sides of 4
units
