RTI 1.3 & 1.4 INTRO TO TRANSF. & REASONING AND PROOF

What is the image of (x, y) after a translation of 3 units right and 7 units down?

• 
  

  $\left(x,y\right)\rightarrow\left(x+3,\ y-7\right)$

• $\left(x,y\right)\rightarrow\left(x+3,y+7\right)$

• $\left(x,y\right)\rightarrow\left(x-3,\ y-7\right)$
  

• $\left(x,y\right)\rightarrow\left(x-3,y+7\right)$
  

Point (7,2) is translated vertically 2 units and horizontally -5 units. Where is the new point located?

Use the rule (x,y)-->(x+a,y+b)

• (9,-3)

• (2,4)

• (2,0)

• 12,4)

Triangle ABC is going to be translated. Where would A' position be at, if the translation was be (x,y) --> (x+3, y-2)?

• (-1,3)

• (5,3)

• (5,8)

• (3,5)

Answer explanation

The point that is to be transformed is called the:

• Pre-Image
• Image
• Post-Image
• Transformation
