Question

Check my answer! Fan and Medal. I written it out.

Answer 1

Answer:


Translating...

In the X coordinate, you would either move left or right. Left means subtract, Right means add. So when I see add 1, I can infer that I am moving to the right.

In the Y coordinate, you would move, or jump, up or down. Up is to add, down is to subtract. Since it is subtracting 5, I can tell that it is moving down 5.

X = 4, Y = 2.

These are the isolated variables: X and Y. Since we know know the isolated values, it isn't so isolated.

4 + 1 = 5, 2 - 5 = -3. So, the now translated value, (4,2), is (5,-3).

(4,2) ---> (5,-3).

Expanded:

4,2 -> ( x + 1, y - 5) -> (5,-3)

--------------------
Part A) Since point A, or original point A, is (+,+), it would be quadrant I, or 1.

Part B) I translated it up above. The now translated coordinates for A, or now A', is (5,3). Since this is (+,-), it would be Quadrant IV, or 4.

Part C) IF being reflected on the y-axis, it would be - I -. Simpler words, The coordinate would appear on the Quadrant that is side from the original one. Example: one coordinate was (-,+), which is located in Quadrant II (two). Reflected over the y axis, would be (+,+). Why is that? Well, the Y - axis is where you jump, therefor the line going vertical. We basically go over that line, and that would be, reflected over the y axis.

Same to reflected over the x-axis. Where we jump, is the x axis, or the line that is horizontal. We go over that line, therefore giving it the term, reflection over the x- axis. Example: (-,+), or Quadrant II, would reflect to Quadrant III, or (-,-) if is being reflected across the 'x'-axis.

So if A' was (5,-3), reflected over the y-would be (-5,-3).

Reflected over the x-axis would be (5,3).

Quadrant A' is being reflected over by the y-axis: Quadrant III.

Over x-axis: Quadrant I.

Answer 3

It's correct. I dunno why part C is so long though, should be just A'(5,-3) -> A''(-5,-3) so quadrant 3.

Thanks, I like exaggerating my point, usually it gets me extra credit. I like testing challenging knowledge, thanks!
