Question

Image point B'(4, -8) was transformed using the translation (x - 2, y + 3). What were the coordinates of B?



(2, -5)

Answer 1

Hint:

\((x,y) \rightarrow (x-2 , y+3)\)

Answer 2

B = (x,y)
B' = (x-2),(y+3)

Answer 3

im lost how do i solve that

Answer 4

B' = (4,-8) and B' = (x-2,y+3),
Therefore,

(4,-8) = (x-2 , y + 3)

Therefore

x - 2 = 4
y + 3 = -8

Solve for x and y

Answer 5

If that doesn't make sense, you might need a tutor.

Answer 6

It's not that simple @cunningham2000. Look closer and you'll see why.

Answer 7

i got x=6 and y =5

Answer 8

-5

Answer 9

x = 6 is correct. y = -5 is not correct.

Answer 10

I actually thought it should be the opposite, but I thought she was given the correct answer.

Answer 11

No, she was given a list of choices to choose from.

Answer 12

Add 2 to the translated x to get back to the original x point. Subtract three to get back to the original y.

Answer 13

@cunningham2000, you need to be able to explain the process of why she must do that.

Answer 14

so 5

Answer 15

sorry @miadeex, y = 5 is not correct either.
