Take out your H.W. (in packet).
Somewhere on page 65 of packet, write this definition:
conjecture: mathematical statement that is a good guess or an idea about a pattern (an educated guess in math).
*Don’t need to copy the picture.

3. OBJECTIVE(S):
SWBAT
February 5, 2015
Thurs., Day [D]
Recognize that when two ordered pairs differ only by the sign of one or both of the coordinates, then the locations of the points are related by reflections across one or both axes.

4. Similar- same absolute value ( 2 units from zero on the # line)
Lesson 16: page 65

Thurs., Day [D]
Teacher's sample answer:
2 and -2
Similar- same absolute value ( 2 units from zero on the # line)
Different- on opposite sides of zero.

5. Page 65 - Classwork (10 minutes)
Same y-coordinates.
The x-coordinates have the same absolute value.  
(-3,4)
(3,4)
The x-coordinates are opposite numbers.

6. Page 66
Both points are 4 units above the x-axis and 3 units away from the y-axis.
(-3,4)  
(3,4)
One point is 3 units to the right of the y-axis; the other is 3 units to the left of the y-axis.
x-coordinates are opposite numbers, so the points lie on opposite sides of the y-axis.
Because opposites have the same absolute value, both points lie the same distance from the y-axis.
points lie the same distance above the x-axis, so the points are symmetric about the y-axis.

8. Page 66 - Classwork (10 minutes)
When the coordinates of two points are (x, y) and (-x, y), what line of symmetry do the points share? Explain.
They share the y -axis because the x -coordinates are the same and the x -coordinates are opposites, which means the
points will be the same distance from the y -axis but on opposite sides.  
(-3,4)
(3,4)

9. Page 66 - Classwork (10 minutes)
When the coordinates of two points are (x, y) (3, 4) and (x, - y) (3, -4), what line of symmetry do the points share? Explain.
They share the x -axis because the x -coordinates are the same and the y -coordinates are opposites, which means the
points will be the same distance from the x -axis but on opposite sides. 

(3, -4)

Possible answer:
Begin at (0, 0) and end at (5, -1).
Use exactly one reflection.

Closing
What is the relationship between (5, 1) and (5, -1)?
Given one point, how can you locate the other?
If you start at either point and reflect over the x-axis, you will end at the other point.
