Video 2 - Translating Points

Multiple Choice

Evidence of Learning.

If you translate point A(x, y) to the left 3 units, what would be the coordinates of the point A'?

• $A'\left(3,\ y\right)$

• $A'\left(x+3,\ y\right)$
  

• $A'\left(x-3,\ y\right)$
  

• $A'\left(x,\ y-3\right)$
  

Make sure to copy this table down onto your notebook page 16. We will reference this table throughout the unit.

What are the coordinates of point X'Y'Z'? 
And, what is the rule for this translation. 

Open Ended

What is the rule for the translation from Trapezoid QRST to Trapezoid Q'R'S'T' ?

notice the change in the x-values in the coordinates

Open Ended

What is the translation rule from figure A to figure A'?

notice that both the x-value and y-value changed because it was a combination of a horizontal slide and vertical slide

Multiple Choice

Determine the correct translation rule?

• $\left(x,\ y\right)\rightarrow\left(x-7,\ \ y\right)$

• $\left(x,\ y\right)\rightarrow\left(x+7,\ \ y\right)$

• $\left(x,\ y\right)\rightarrow\left(x,\ y-7\right)$

• $\left(x,\ y\right)\rightarrow\left(x,\ y+7\right)$

Multiple Choice

Determine the translation rule?
