Question

Which rule represents the translation of hexagon DEFGHI to hexagon D'E'F'G'H'I'?

(x, y)→(x + 4, x – 2)

(x, y)→(x – 7, y + 7)

(x, y)→(x + 2, x – 4)

(x, y)→(x + 7, y – 7)

Answer 1

Pick a letter, any letter (of this list)

Answer 2

ohh okay brb sorry

Answer 3

sorry about that, I got distracted for a second

Answer 4

let me know when you want to start

Answer 5

k im back but i think it is the last one because u add 7 to y which will take u to the right and then downward 7 for y

Answer 6

you nailed it, so the answer is...?

Answer 7

oh nvm, you already said it's the last one

Answer 8

so choice D is your answer

Answer 9

(x, y)→(x + 7, y – 7)

Answer 10

you got it, very nice work

Answer 11

thank u :)

Answer 12

you're welcome

Answer 13

here is the next one :

Which two transformations are applied to pentagon ABCDE to create A'B'C'D'E'?

translated according to the rule (x, y) → (x + 7, y + 1) and reflected across the x-axis

translated according to the rule (x, y) → (x + 1, y + 7) and reflected across the axis

translated according to the rule (x, y) → (x + 7, y + 1) and reflected across the y-axis

translated according to the rule (x, y) → (x + 1, y + 7) and reflected across the y-axis

Answer 14

if we move the figure over to the right 7 units, we're adding 7 to each x value. This will place the figure directly underneath the new figure

Answer 15

So x --> x+7

Answer 16

Now notice how the point A' is 1 unit away from the x axis. So we need to move A so that it is 1 unit away from the x axis as well (so we can do a proper reflection)

Answer 17

so this means we need to move the points up one unit, so y --> y+1

Answer 18

since x --> x+7 and y --> y+1, the transformation is (x,y) --> (x+7, y+1), with me so far?

Answer 19

ya writing it down lol thank u

Answer 20

Alright, just wanted to be sure


So we have (x,y) --> (x+7, y+1)


This will translate the original figure directly underneath the new figure. To complete the transformation, we then follow with a reflection over the x axis


So the answer is choice A

Answer 21

ohh okay it the same thing just in a different location and ur trying to figure out the coordinates makes since

Answer 22

If quadrilateral L'M'N'O' represents the reflection of quadrilateral LMNO across the line y = x, which point is at the ordered pair (-1, 1)?

N'

O'


L'

M'

Answer 23

To reflect any point (x,y) across the line y = x, all you do is swap the x and y coordinates

So (x,y) ---> (y,x)

So we know (x,y) ---> (-1, 1), what is the value of (x,y)?

Answer 24

i have no idea to be honest with u

Answer 25

probably the strange notation that's getting you...notice point N (1, -1)


Use the rule (x,y) ---> (y,x) to get


N ---> N'

(1,-1) ---> (-1,1)


So N' is at the point (-1,1)


You can find this by trial and error or by going backwards from the answer (then going forwards)

Answer 26

okay so the answer would be n im sorry im trying to figure it out :/

Answer 27

no it's N', so you are close

Answer 28

oh I think that's what you meant

Answer 29

lol ya thats what i meant i just did it lower case lol

Answer 30

i gotcha lol

Answer 31

If trapezoid JKLM is translated according to the rule (x, y) → (x + 8, y - 3), what are the coordinates of point L'?

(1, -5)

(-10, 6)

(-5, 3)

(6, -8)

Answer 32

What is point L

Answer 33

Ie what are the coordinates of point L

Answer 34

-2, -5

Answer 35

Good, so (x,y) ---> (x+8, y-3) tells us to add 8 to the x coordinate and subtract 3 from the y coordinate

Answer 36

okay so it would then be 6, -8

Answer 37

you got it

Answer 38

i do??

Answer 39

yes, the answer is choice D

Answer 40

cool thank u


If triangle XYZ is reflected across the line y = 1 to create triangle X'Y'Z', what is the ordered pair of X'?

(1, -5)

(1, -3)

(1, 3)

(1, 5)

Answer 41

The y coordinate of X is y = -3

The distance y = 1 is from y = -3 is |-3-1| = 4 units

So we need to add 4 units to y = 1 to get y = 1+4 = 5

This means that X' is at the point (1,5)

Answer 42

hmm now that I look at it, it might be a bit confusing (with the notation). Let me know what you think.

Answer 43

i get that

Answer 44

alright great

Answer 45

thank u so much u r a great help seriously u dont even know i wish u were my teacher

Answer 46

If trapezoid T'U'V'W' represents trapezoid TUVW reflected over the y-axis, the ordered pair of W' is

Answer 47

To reflect ANY point over the y axis, you simply change the sign of the x coordinate

So (x,y) ---> (-x,y)

Ex: (1,2) reflects over the y axis to (-1,2)

Note: the answer isn't (-1,2), this is just an example

Answer 48

okay lol

Answer 49

so what did you get for the answer?

Answer 50

-3,222

Answer 51

-3,2

Answer 52

well W is (2,3), so W' should be (-2,3)

Answer 53

You only change the sign of the x coordinate when you reflect over the y axis

Answer 54

oh okay i understand

Answer 55

that's great :)
