Question

alibaby
A polygon is shown on the graph:

If the polygon is translated 2 units down and 4 units left, what will the coordinates of the new image be? Use prime notation in expressing the new coordinates.

Answer 1

Answer 2

@Alibaby Make sure you go back on the other answer, I given you something else to look at and finish the question. You must add the fact that it will not change in size, measurement in angles/lengths and such, but only LENGTH, hence its a rigid transformation.

Answer 3

shift down/up will change the y-value, shift right/left will shift the x-value
shifts down/left will be negative
shifts up/right will be postiive

Answer 4

HUH

Answer 5

Translation? Easy, what does it say?

Key words: DOWN 2


Down or up signals - or + to y.

Left and right signals - or + to x.


Down: - y

Up: + y


Which would it be?

Answer 6

Now, for the x factors,


Left: - x

Right: + x

Answer 7

So,

( x - 4, y - 2)

Answer 8

So if you have the original coordinates of A(1,5), B(0,1), C(6,1), and D(5,5), and a shift 2 units down and 4 units left, what would the resulting coordinates be?

Answer 9

2 units down = y - 2
4 units left = x - 4

Answer 10

So just apply this to each coordinate: (x,y) --> (x - 4, y - 2)

Answer 11

Are you getting this @Alibaby

Answer 12

What studygurl listed.

Now do the formula with the explanation I given you first.

(1 - 4, 5 - 2)

Answer 13

yes

Answer 14

So what would the new coordinate for A be?

Answer 15

Also, remember,


after you get the new coordinates for A, the prime notation form would be A'. For prime notations, you just add the '.

Answer 16

Do you want me to reveal A'?

If you get your answers, tell me, and I will help you check. (By the way, I gotten 50/50 on this test, therefore you can trust me. Let me guess, module 2?)

(x - 4, y - 2)

A: (1,5) ---> (1 - 4 = -3, 5 - 2 = 3.) ---> ANSWER: A': (-3,3)


For coordinate A, it would be A' (-3,3)

(DO NOT FORGET ' TO SIGNAL PRIME NOTATION.)


B: (0,1) ---> ( 0 - 4 = 0, 1 - 2 = -1) ---> ANSWER: B' (0,-1)


Can you handle C and D and turn it to C' and D'?
