Question

Plot the points of the pre-image and graph the pre-image.

Answer 1

Given:

The Point is:

$\begin{gathered} W(2,2) \\ \\ X(2,0) \\ \\ Y(0,1) \\ \\ Z(1,2) \end{gathered}$

The scale factor is 3.

Find-:

Create the point W'X'Y'Z'

Explanation:-

The scale factor is 3.

So the point is:

$\begin{gathered} W^{\prime}=3W \\ \\ W^{\prime}=3(2,2) \\ \\ W^{\prime}=(6,6) \end{gathered}$

Point X' is:

$\begin{gathered} X^{\prime}=3X \\ \\ X^{\prime}=3(2,0) \\ \\ X^{\prime}=(6,0) \end{gathered}$

The point Y' is:

$\begin{gathered} Y^{\prime}=3Y \\ \\ Y^{\prime}=3(0,1) \\ \\ Y^{\prime}=(0,3) \end{gathered}$

The point Z' is:

$\begin{gathered} Z^{\prime}=3Z \\ \\ Z^{\prime}=3(1,2) \\ \\ Z^{\prime}=(3,6) \end{gathered}$

The graph of WXYZ.

The graph of W'X'Y'Z'
