Point A(4,2) is translated according to the rule (x,y)-->(x+1,y-5) and then reflected across the y axis

a)In which quadrant of the coordinate plane is point A located?

b) What are the coordinates of translated point A'? in which quadrant of the coordinate plane is point A' located?

c)What are the coordinates of the reflected point A"? In which quadrant is point A" located?

I just want to know what the apostrophes mean after the "point A"

  2. it just numbers the transitions. for example: slide the point A to the right. the coordinates would be labeled A.
    now reflect it. the new point would be labeled A'.
    now slide toe the right. new point is now labeled A''. and so on.

  3. (4,2) is in the first quadrant

    (5, -3) is in fourth quadrant, lower right

    across y axis, same y, change sign of x
    (-5,-3) quadrant III

  4. A(4,2) gives the coordinates of a point labeled A
    From the origin, it is 4 units to the right and 2 units up .

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

    reflection across y-axis
    (x,y) --> (-x,y)
    (5,-3) --> (-5,-3)

  18. They were right, when they posted it. Then they changed them. Changed them again. And again. You just have to know it, I'm pretty sure the short answer questions are still the same.
