13. Which describes the transformations that could be used the create the pattern shown?
Answer: D translation, reflection and rotation
14. Find the coordinates of the image of the point. C(-5,3); rotation 90° counterclockwise about origin, reflection in the y-axis.
Initinal point C(-5,3)
The point after rotation 90° counterclockwise about the origin
When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A'(-y,x). In other words, switch x and y and make y negative.
Therefore C'(-3,-5)
The point after reflection in the y-axis.
(x,y)---> (-x,y)
This means C'(-3,-5) will change to C"(3,-5) Option C
