Question

Which equation can pair with x – y = –2 to create a consistent and dependent system?

Answer 1

Probably the inverse equation

Answer 2

Politely disagree with the previous response. If two equations form a consistent + dependent system, then both equations are mathematically equal (a.k.a y = x, and 2y = 2x, as these both represent the same line)

apply this logic to your problem to see which answer choice is equivalent to x – y = –2 (you may need to play around with adding/subtracting/multiplying/dividing the equation by constants)
