Which equation represents a line that has a slope of One-third and passes through point (–2, 1)? y = one-third x minus 1 y = one-third x + five-thirds y = one-third x minus five-thirds y = one-third x + 1

Enter the number of complex zeros for the polynomial function f(x) = x 4+ 5x² +6

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- 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. 3- 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 part b?
