Answe 1. choose the equation of the vertical line passing through the point (−2, 3). y = 3 x = 3 y = −2 x = −2 2. the domain of the following relation: r: {(−4, 8), (8, 10), (5, 4), (1, 6), (5, −9)} is {8, 10, 4, 6, −9} {−4, 1, 5, 8} {−4, 8, 5, 1, 5} no domain exists

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?
