19. 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 reflected point A’’? In which quadrant of the coordinate plane is point A’’ located?

(3 points)

I don't want the answer, I just want how I would solve all three of these steps. I'll do the math myself thanks!!! :-D
I also want to know what they mean by A' and A''???

    Please help this is due today and I'm really confused.

  • Math - ,

    (4,2) is in QI

    since (x,y)->(x+1,y–5)
    (4,2)->(4,-3) so it is in QIV

    reflection in the y-axis flips the x-coordinate:
    (x,y)->(-x,y)
    So, (4,-3)->(-4,-3) in QIII

    Well I just asked for an explanation and not an answer but thanks! It helps a lot.
