What is 600,000,000 in scientific notation ?

Aline passes through the two given points. is it vertical , horizontal , or neither ? (5, 2), (-5, -2)

This is so hard and it’s for a test

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?
