Draw transformed figures and specify transformation sequences mapping one figure to another.
Find a missing coordinate from a transformation rule
Problem
Find the missing coordinate when \(3,~5\) is mapped by translation by \(<4,-2>\) to \((a,3)\).
Big Picture
What this problem is really about
Treat a coordinate rule as two parallel equations, one for each coordinate position. Apply the horizontal component only to the source x-value and the vertical component only to the source y-value, form the complete image, and then match corresponding positions with the partially known ordered pair.
