Transformation involves changing the position of a shape
The transformations and the order in which they were applied are:
A. 90° counter-clockwise rotation, then reflected across the y-axis
From the figure, the coordinate of RST is:
[tex]R= (2,4)[/tex]
[tex]S = (2,8)[/tex]
[tex]T =(-6,8)[/tex]
Using R to illustrate the transformation.
We have
[tex]R= (2,4)[/tex]
First, R is rotated 90 degrees counterclockwise
The rule of this transformation is:
[tex](x,y) \to (-y,x)[/tex]
So, we have:
[tex](2,4) \to (-4,2)[/tex]
Next, the point is reflected across the y-axis.
The rule of this transformation is:
[tex](x,y) \to (-x,y)[/tex]
So, we have:
[tex](-4,2) \to (4,2)[/tex]
From the question, we have the coordinate of R" to be;
[tex]R: =(4,2)[/tex] --- same as the result of the above sequence
Hence, option (A) is correct
