Question

1. The figures below represents which type of transformation? A. Translation up 10 units. (x,y) → (x,y+10) B. Reflection across the y-axis. (x,y) -(-x,y) C. Rotation 1809(x,y) → (-x,-») D. Reflection across the x-axis. (x,y) → (x,-»)

Answer 1

according to the image if we take a referal point like A,

we can see what happened with the transformation

A=(-3,-5)

A'=(-3,5)

We can see that the x coordinate stayed the samen but the y coordinate changed its sign, meaning that this is a reflection over the x-axis.
