Question

Point Q has coordinatęs (4,3). Reflected over Rx-axis (Q), what are the coordinates for Q?A. (4,-3)B.(-4,-3)C.(-4,3)D.(4,-3)

Answer 1

Answer:

A. (4,-3)

Explanation:

A reflection over the x-axis does the following transformation.

$(x,y)\rightarrow(x,-y)$

Now, if we are reflecting Q(4, 3) over the x-axis, the coordinates will transform according to the above rule and the coordinates of the image will be

$(4,3)\rightarrow(4,-3)$

which is choice A.
