Which system is represented by the graph? a. y= 3x + 2 , y= 3x - 1 b. y= 1/3x + 2 , y= 1/3x - 1 c. y= -3x + 2 , y= -3x - 1 d. y= 3x - 2 , y= 3x + 1

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
