High school geometry
A translation acting on the coordinate plane takes the point (-169,434) to point (-203, -68). What are the coordinates of the image of point (31, -529) under this translation?. Created by Sal Khan.

- First you need to find out the translation. Then apply it to the point. If you think about it it's just an extended version of the previous problems.(4 votes)
- I don't get translations and how are we going to use this in life(3 votes)
- Well, every time you move, you translate to a different space. When you drive to school, you translate (ex, a block to the right, and three blocks ahead).(5 votes)

- do you just subtract everything or are you supposed to add and then subtract(2 votes)
- I can not understand it:
This is my thinking:31-(-34)=31+34=65
The number 34 and 502 are negitive,right?(2 votes)
- The -34 and -502 are the rules for the translation. Whatever pint you're translating, you add -34 to the x-coordinate and -502 to the y-coordinate. Subtracting instead of adding would give you the opposite effect, and translate the point up and to the right instead of down and to the left.(4 votes)

- why cant you use the blue coordinates first? (subtract the magenta from the blue)(0 votes)
