Consider the graph of the linear function h(x) = –x + 5. which could you change to move the graph down 3 units? the value of b to –3 the value of m to –3 the value of b to 2 the value of m to 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?
