PLEASE SOLVE THIS QUESTION WITH FULL SOLUTIONS SHOWN for what value(s) of a will the line joining points (-2,-1) and (3,5) be parallel to the line ax-(a-1)y=2?

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′.
