Dilation involves changing the size of a shape.
See attachment for the graphs of the image and the pre-image
The coordinates of the triangle is given as:
[tex]\mathbf{X = (-3,2)}[/tex]
[tex]\mathbf{Y = (2,3)}[/tex]
[tex]\mathbf{Z = (1,-1)}[/tex]
The scale factor (k) is given as:
[tex]\mathbf{k = -3}[/tex]
So, the coordinates of the image are:
[tex]\mathbf{X' = -3 \times (-3,2)}[/tex]
[tex]\mathbf{X' = (9,-6)}[/tex]
[tex]\mathbf{Y' = -3 \times (2,3)}[/tex]
[tex]\mathbf{Y' = (-6,-9)}[/tex]
[tex]\mathbf{Z' =-3 \times (1,-1)}[/tex]
[tex]\mathbf{Z' =(-3,3)}[/tex]
So, the coordinates of the image are:
[tex]\mathbf{X' = (9,-6)}[/tex]
[tex]\mathbf{Y' = (-6,-9)}[/tex]
[tex]\mathbf{Z' =(-3,3)}[/tex]
