Answer 3

well, we might want to consider moving one onto the other to get an idea .... any thoughts one a convenient start ?

Answer 4

well I'm redoing this for a better grade, but the first time my answer was x + 2, y + 2

Answer 5

to have a reflection over the x-axis the x value stays the same and the y-value moves to -y example a point (2,3) will move to (2, -3) (x, y) goes to (x, -y)

Answer 6

well, since we are trying to get the top towards the bottom, and flipped, id say we line up the C points

x+2, y-2 should at least get us that far

Answer 7

then using C as a pivoting points, we can find the midpoint between A and A', or B and B'

and use that to define the line of reflection

Answer 8

but doesn't it say that the student already did a reflection? I don't get it shouldn't I just move it two spaces to the right and two down?

Answer 9

oh, yeah it does say that .... these old eyes of mine

Answer 10

but then I don't understand why I got it wrong

Answer 11

there is no real good way to approach this since the original setup is not well defined.

Answer 12

the student did a reflection so now you are at A'B'C' and need to get to A"B"C"

Answer 13

so ABC is the result after the student reflected it?

Answer 14

C is defined well enough, but A and B are not ....

Answer 15

ABC is the start, the other is the end

Answer 16

I just don't understand if ABC is before or after the student reflected it

Answer 17

it seems youve got a better bead on it, your movement is bad most likely due to the interval seperation along the axises

Answer 18

ABC is before reflection

Answer 19

review my response for example C(4,4) is now at (4, -4) but C" is at (6,2) so moved (x + 2, y + 6)

Answer 20

to complete the move need to go from A'B'C' to A"B"C" need 2 places right and 6 places up
