Ineed the coordinates of each point under the given transformation

What properties allow transformation to be used as a problem solving tool

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.

3x + 4y = 5 x- 3y = -7 solve by substitution
