Question

(x,y)→(x-234) (y+1239) describe what that means

Answer 1

\[\large \bf (x,y) \rightarrow (x-234,y+1239)\] For the point (1000,1000)\[\large \bf (1000,1000) \rightarrow (1000-234,1000+1239) \rightarrow (766,2239)\]

Answer 2

Basically, you subtract the x point by 234 and add the y point by 1239.
