Answer:
First option is correct. The location of point A after the transformations is (-5,1).
Step-by-step explanation:
It is given that the coordinates of point A are (-5,1).
Rectangle ABCD is reflected over the x-axis. then x-coordinate remains the same but the sign of y-coordinate is changed.
[tex](x,y)\rightarrow (x,-y)[/tex]
Coordinates of point A are
[tex](-5,1)\rightarrow (-5,-1)[/tex]
After that ABCD is reflected over the y-axis, then y-coordinate remains the same but the sign of x-coordinate is changed.
[tex](x,y)\rightarrow (-x,y)[/tex]
Coordinates of point A are
[tex](-5,-1)\rightarrow (5,-1)[/tex]
After that ABCD rotated 180 degrees about the origin, then the sign of both coordinates are changed.
[tex](x,y)\rightarrow (-x,-y)[/tex]
[tex](5,-1)\rightarrow (-5,1)[/tex]
Therefore option 1 is correct.
