Explanation of Solution

Given information :

Graph :

  

Interpretation :

Line passing through the point “2” is the line of reflection.

b.

To determine

To Check : Whether $AB=BA\text{'}$ ?

Explanation of Solution

Given information :

Proof :

As we can see that

  

Line passing through the point “2” is the line of reflection. Thus, $AB\ne BA\text{'}$

c.

To determine

The role of the point B.

Answer to Problem 13PSB

Point B is the image of the point A.

Explanation of Solution

Given information :

Calculation :

As we can see that

  

Line passing through the point “2” is the line of reflection.

Thus, point B is the image of the point A.
