What is the difference between the point (6,-3) and (6,5)?

Find the value of x for which abcd must be a parallelogram -9-6x x-30

Ineed to know the answer to this algebra question.

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′.
