Chapter 14.5, Problem 6WE

To determine

To find the coordinates of the images A, B and C by the given dilation.

Answer to Problem 6WE

The coordinates after dilation are $A\text{'}\left(6,0\right),B\text{'}\left(4,2\right)\text{ and }C\text{'}\left(2,-2\right)$ .

Explanation of Solution

Given information:

The coordinates of A, B and C are:

  

The given dilation is $D_{O,1}$ .

Calculation:

The solution can be obtained by:

  $\begin{array}{l}A\text{'}=1\cdot A\left(6,0\right)=A\text{'}\left(6,0\right)\\ B\text{'}=1\cdot B\left(4,2\right)=B\text{'}\left(4,2\right)\\ C\text{'}=1\cdot C\left(2,-2\right)=C\text{'}\left(2,-2\right)\end{array}$

Hence, the coordinates after dilation are $A\text{'}\left(6,0\right),B\text{'}\left(4,2\right)\text{ and }C\text{'}\left(2,-2\right)$ .
