A single transformation that describe the image is
a dilation with a scale factor of -0.5 and center of dilation of (1, 2)
What is dilation
A scatter plot is a type of graphical representation used to display the relationship between two continuous variables.
The center of dilation is the point where by the lines passed, investigating the figure shows that it is at (1, 2)
Since the figure is inverted this is a negative scale factor
Taking one of the sides as reference, the dilation factor is found to be half
