Answer 2

@Vocaloid

Answer 3

reflect across the x-axis first

then translate right and up as needed

Answer 4

ok so first lets figure out what the sequence of transformations that changes figure ABCD to figure A'B'C'D'.

Answer 5

well the first step is to write the sequence of transformations that changes figure ABCD to figure A'B'C'D'.@Vocaloid

Answer 6

those are the steps

Answer 7

it's up to you to figure out the numbers

Answer 8

ok...
um how do i find the numbers.. ?

Answer 9

what are the coordinates of ABCD after a reflection across the x-axis?

draw it out if you need to

Answer 10

um idk.. how to figure that out..

Answer 11

draw it

Answer 12

but thats the problem i dont know what to do at all? i dont even know what to draw..

Answer 13

what are the coordinates of A, B, C, and D?

Answer 14

what are coordinates?

Answer 15

the x and y values

Answer 16

ok and how do i find the coordinates of abcd?

Answer 17

look at the original graph

flip the points across the x-axis

then look at the graph to see what the x and y values of each point are

Answer 18

ok ill try.. 0,2?

Answer 19

which point are you talking about?

Answer 20

A

Answer 21

x value comes first

Answer 22

2,0

Answer 23

what's the x value of point A?

Answer 24

-4

Answer 25

good, what's the y value?

Answer 26

2 and 1/2?

Answer 27

look at the original graph

Answer 28

-4

Answer 29

nope

Answer 30

y value

Answer 31

ignore the transformation stuff, just look at the original problem

Answer 32

4

Answer 33

good

to do a reflection across the x-axis we simply multiply the y-coordinate by -1, giving us a value of -4

so the coordinate of A AFTER the transformation is (-4,-4)

Answer 34

repeat the same process with B C and D

Answer 35

ok b is (5,2)?

Answer 36

where is 5 coming from

Answer 37

what's the x value of B?

Answer 38

(look at the ABCD figure NOT the A'B'C'D figure)

Answer 39

oh wait sorry.. -2

Answer 40

good, what's the y?

Answer 41

2

Answer 42

good

so the coordinates are (-2,2) BEFORE transformation
what are the coordinates AFTER transformation?

Answer 43

(if you are unsure, see what we did with point A)

Answer 44

5,-2

Answer 45

nope, see what we did with point A

Answer 46

like I said, ignore the A'B'C'D figure

Answer 47

i dont get how to find it after the transfromation..

Answer 48

use this process to find point B after the transformation

Answer 49

ok so -5,-2?

Answer 50

no

Answer 51

the coordinates of point B are (-2,2) BEFORE the transformation

so the coordinates of point B AFTER the transformation are...?

Answer 52

2,-2?
