Question

PLSSS HELP WILL MARK BRAINLIEST!! :) Reflections. if you don't kno don't put anything :) there's no graph :)
If point P(2,-4) is reflected over the x-axis, determine the coordinates of the image.

(-2, -4)
(-4, 2)
(4, 2)
(2, 4)

Answer 1

Answer:

(2,4)

Step-by-step explanation:

the x values stays the same because you are reflecting over its axis. the 4 becomes positive

Answer 2

Step-by-step explanation:

Algebra Explanation: If something is reflected over the x axis, the x coordinate's sign will stay the same while the y coordinate sign will switch.

Using this info, the answer will be (2,4)

Geometric Explanation: Point P is in Quadrant 4. If we reflect a point about the x axis, it can only go to Quadrant 1. Quadrant 1 has a positive x and positive y. So this eliminates the first 2 options.

Reflecting across a line will align the pre image and current image with each other. This means the x coordinate and y coordinate will stay in the same place. So (2,4) is the answer.
