Graph Paper Set-up1) Fold the graph paper the same way you do with the openings/closings sheets to create six boxes.
2) Create a large x and y-axis in one box.
3) Label each axis. (Top and right).
x
y
4) Use the light blue lines of the graph paper to make evenly spaced tic marks along both axes.
5) Label numbers for each tic mark underneath/to the right. DO NOT LABEL 0!!!
-3 -2 -1 1 2 3
21
-2
6) Repeat steps 1 – 5 for the remaining left side boxes.
Translating on a Coordinate Plane
Write this on the front/top of your graph paper. Write a #4 on the top
right corner of this graph paper.
Example 1: Translate A (3,-2) 3 units to the left and 4 units down.
A(3,-2)A’ = A Prime (the new point)
A’(0,-6)
A
A’
Example 2: Translate B (-4,-5) 2 units to the right and 1 units up.
B (-4,-5) B’(-2,-4)
B’B
Example 3: Translate when B(-2,1) & C (2,1) 4 units to the right and 2 units down.
B (-2,1)C (2,1)

Example 6: Translate Quadrilateral ABCD 2 units to the left and 6 units down.
A(-1, -5) B(0, -3) C(3, -2) D(4, -4)
A(1, 1)B(2, 3)C(5, 4)D(6, 2)
Homework
