Answer: The slope of A'B' is 3.
Explanation:
- We know that when a geometric figure is dilated by a scale factor (k) then the corresponding sides ( of pre-image and the image ) are parallel.
Given : AB is dilated by a scale factor of 3 to form A'B'. Point which lies on AB is the center of dilation.
Here, AB is corresponding side to A'B'.
⇒ Slope of AB= Slop of A'B'
Also, it is given that : The slope of AB is 3.
⇒ Slop of A'B' =3
Therefore , the correct answer is : The slope of A'B' is 3.
