Translations

Hello!!! I really need help learning about translations. Say you have this problem:

Point M(4,3) is translated according to the rule (x,y)-->(x+2,y-5). What are the coordiniates of point M?

Could someone solve this for me and tell what the answer is and why?

Thanks,

ShyClaw

hi shyclaw,

Point M(4,3) is translated according to the rule (x,y)-->(x+2,y-5). What are the coordiniates of point M?

That means that 4 becomes x+2 = 6 and 3 becomes y-5 = 3-5 = -2.  So the new coordinates of M are (6,-2)

Strictly (if that's exactly how the question is worded) the answer for the coordinates of M is (4,3).  But I assume they wanted what it becomes after the translation.
