Lesson 3: Translations

# Translating points

Translations are defined by saying how much a point is moved to the left/right and up/down.

• l can't understand this make it simple for you to get it
• You literally just move it. If asked to translate a point (x+1,y+1), you move it to the right one unit because + on the x-axis goes to the right, and move it up one unit, because + on the y-axis goes up. Now, if asked to translate (x-1,y-1) You move it to the left one unit since - on the x-axis goes to the left, and move it down one unit since - on the y-axis goes downwards.
• how do i solve the equation when they dont even give me an x and y axis?
• Here are some tips:
Look at the numbers. You are doing addition and subtraction! Remember that moves up and to the right mean adding to the number, and moving down and to the left means subtracting.
If all else fails, draw a graph on a scrap piece of paper.
• So it is currently 10/18/21 at pm (Pacific time). How many years will it take for someone to respond to me?
• I feel bad for you not getting any responses. I know how you feel. But right now, you just got a response from me! Hallelujah!
• I understand this but when i go the quiz I don't understand nothing
• I don't understand where "Sal" got all these numbers from. im confused...?
• The numbers he mentioned were, essentially, the coordinates of the points.
• What happens if one goes left and the other goes up?
• Then it is no longer a translation. For a translation to be possible, all must move the same distance
• these is like a formula
• (x, y) → (x + 7, y - 1)
