Question

reflecting a shape over the y - axis will flip it in which direction? a. diagonally b. perpendicularly c. horizontally d. vertically

Explanation:

When reflecting a shape over the y - axis, the x - coordinates of its points change sign while the y - coordinates remain the same. This results in a horizontal flip. For example, a point (x,y) becomes (-x,y). Diagonal flipping is not related to y - axis reflection. Perpendicularly is too general a term and not the correct description here. Vertical flipping is related to x - axis reflection.

Answer:

c. horizontally
