Which algebraic rule will produce a translation that only moves 5 units to the left?

• (x, y) --> ( x , y - 5)

• (x, y) --> ( x - 5 , y + 5)

• (x, y) --> ( x - 2 , y - 5)

• (x, y) --> ( x - 5 , y)

Where is the location of A' after a transformation that follows the rule:

(x, y)  $\rightarrow$   (x + 3, y - 2)

• (-1, 3)

• (5, 3)

• (5, 8)

• (3, 5)

Complete the rule for the transformation

 (x, y)  $\rightarrow$  

•  (x -1, y + 2)

•  (x -2, y + 1)

•  (x + 2, y - 1)

• (x + 1, y - 2)

Write the rule for this translation:

Slide 3 up and 2 to the left.

• $\left(x,\ y\right)\rightarrow\left(x+3,\ y-2\right)$

• $\left(x,\ y\right)\rightarrow\left(x-2,\ y+3\right)$

• $\left(x,\ y\right)\rightarrow\left(x+2,\ y+3\right)$

• $\left(x,\ y\right)\rightarrow\left(x+3,\ y+2\right)$

 $\left(x,y\right)\rightarrow\left(x-2,\ y+3\right)$  B' is located at (-2, -4). Where was Point B located if it was translated using the rule:

• (0, -1)

• (-4, -1)

• (0, -7)

• (-4, 1)

Quadrilateral BQVN contains the points:

B(-2, 4) Q(-2, -4) V(2, 4) N(2, -4). If the quadrilateral is translated to the right 2, what will B' be?

• B'(0, 4)

• B'(-4, 4)

• B'(-6, 4)

• B'(-2, 6)

Point K (4, 2) is translated using the rule (x, y)--->(x + 3, y - 1) and then reflected over the origin. What are the coordinates of K"?

• (7, -1)

• (-7, -1)

• (7, 1)

• (-1, -3)

Reflections over the x-axis change the ____-__________. 

• y-coordinate
• x-coordinate
• y-axis
• x-axis
