In the coordinate plan (-6,9) b (3,9) c (3,3) def is shown in the coordinate plan below

The system of equations graphed below has how many solutions? y = 2x + 2

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?
