Direct link to UmaFaLeung's post “I don't get this problem:...” I don't get this problem: Challenge problem A certain translation takes point D (-3, 10) to point D'(-12, 21). What is the image of E(17, -9) under this translation? I tried (-9, 11), since you need -9 to from -3 to -12, and 11 since it's 11 from 10 to 21; I also tried (9, -11). Can someone please explain what i'm doing wrong? Thanks! • (45 votes) sanudatharuna2 3 years agoPosted 3 years ago.

Direct link to JennahKay's post “The challenge problem is ...” The challenge problem is not making any sense, even after watching the video they give you for help. Is there an easier way to understand this or an easier way for it to be explained? • (40 votes) Conner a year agoPosted a year ago. Direct link to Conner's post “You have to take the tran...” You have to take the translation from the first problem and add it to the third coordinate. So if it was point A at (7,12) to point B at (11,4). The translation is (4,-8). Now you apply that to point C at (10,15), 10+4, 15-8. So your final point is at (14,7).

Direct link to Cameron Holbrook's post “If i choose to type only ...” If i choose to type only what i got for a certain point, will it be the same as the other points or will I get it wrong? This confuses me. • (18 votes) avaroyston a year agoPosted a year ago. Direct link to avaroyston's post “It will be the same as al...” It will be the same as all the points moved the same amount. If that makes sense. I just realized this was 5 years ago, oops! (7 votes) Khadejah McCalla 8 years agoPosted 8 years ago. Direct link to Khadejah McCalla's post “To get the translation ve...” To get the translation vector i can use any points ... for example a object point - any image point = Translation Vector... Well nothing seems to change i get the same result with every point.. So i dont have to do it for every point right? Can i just use one and thats it ? • (19 votes) 1140858 a year agoPosted a year ago. Direct link to 1140858's post “Yes you can use any point...” Yes you can use any point. It is best to use a vertex though. Yes you only need to use one point( see https://www.khanacademy.org/math/math1/x89d82521517266d4:transformations/x89d82521517266d4:translations/v/formal-translation-tool-example) (1 vote) JaredIsTronko a year agoPosted a year ago.

Direct link to fizzishun's post “Choosing J, the initial p...” Choosing J, the initial point is at (2,-4). That point then moves to J' at (-2,3) -2-2=-2+(-2)=-4 This would make the translation (-4,7). Please help. This is EXTREMELY frustrating and I can't move ahead until I understand where my mistake is • (14 votes) Sarah Akala 2 years agoPosted 2 years ago.

Direct link to David Severin's post “Where are you getting con...” Where are you getting confused? You are trying to find the vertex from a preimage point (no tic mark) to an image point (with a prime), so you subtract the <x'-x,y'-y> to get a vector, and once you find the vector, all points of a figure will be translated along the same vector. Take the last example using J. J is at (2,-4) and J' is at (-2,3). The translation it moved along would be (-2-2,3-(-4)) or (-4,7). Always make sure you know the preimage and the image that you are translating to. (5 votes) Jordan 6 years agoPosted 6 years ago.
