Question

PLEASE HELP ME! HAVING A FAILURE TO UNDERSTAND


I have to write a rule for the translation of point A to point A' and use that rule to locate points B' and C' (diagram is in the comments)

Answer 1

it should have the form
\[ \large T(x,y)=(x,y)+(a,b) \]
where (a,b) is fixed.

Answer 2

Um....I don't get it

Answer 3

that's a translation.

Answer 4

u have to solve
\[ \large (-4,0)=T(-1,-2)=(-1,-2)+(a,b) \]

Answer 5

okay

Answer 6

I'm still kind of confused.....

Answer 7

Especially since none of my calculators want to solve that equation

Answer 8

well
\[ \large (-4,0)=(-1,-2)+(a,b) \]
\[ \large (a,b)=(-4,0)-(-1,-2)=(-4+1,0+2)=(-3,2) \]

Answer 9

so in general
\[ \large T(x,y)=(x,y)+(-3,2) \]

Answer 10

Okay. I think.

So the translation would be

(x,y)--> (x-3, y+2)......?

Answer 11

right.

Answer 12

Cool. Okay thanks :)

Answer 13

u r welcome
