Pls help In which choice do all three points lie on the same straight line
A. (0,1) (-1,3) (1,3)
B. (4,2) (2,1) (4,-2)
C. (0,0) (8,0) (0,8)
D. (1,2) (2,4) (4,8)

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?
