Write y =(-3/4)x+3 in standard form using integers a) 3x+4y=12 b) 3x+4y= -12 c) 3x-4y= 12 d) -3x+4y= 12

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?
