Help ASAP please estimate the solution of the linear system graphically and check the solution algebraically

x+y=-4
y=3x+16

A:(-5,1)

B:(10,-14)

C:(3,-7)

D:(4,-4)

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′.
