WILL GIVE MEDAL AND FAN FOR THE FIRST TO HELP ME OUT











Which is a rule that describes the translation of a point from (-5, 4) to (-1, 2)?
A) (x,y) -> (x - 4, y-2)
B) (x,y) -> (x +4, y+2)
C) (x,y) -> (x+4, y +2)
D) (x,y) -> (x-4, y+2)

Answer 1

Translation is when the image is the same but just moved.

Answer 2

So draw it out first, and then compare it with all your options.

Answer 3

Or he can just add the values.

-5 to -1 is just x_1 - x_2

-5 - (-1) = value of x + ?

Answer 4

So you can see there is a change in x and y, I guess you don't have to draw it out and just add the values.

Answer 5

And he can do the same with the y values.

Answer 6

I suggest you do it both ways just so you know what's actually going on.

Answer 7

Is it B?

Answer 8

Sorry I mean a because if you were to move it would most likely be going to the right

Answer 9

me think B

Answer 10

-5 -> x-4, -> -5+4 = -1 so that's right
4 -> y+2 -> 4+2 = 6 so no that's wrong Did you put the right coordinates?

Answer 11

was b suppose to be y - 2?

Answer 12

not y+2

Answer 13

yes I think I mistyped

Answer 14

Then yes, its right.

Answer 15

Yes it's b if you mistyped. you definitely misstyped something here.

Answer 16

so I got it right it is B

Answer 17

You didn't, you thought it was y+2 :P

Answer 18

THANX A_A

Answer 19

no I thought it was y-2
