Calculate the slope of the line through the two points given: a. (-3, 5) and (3, -4)
b. Without graphing the line, is the line slanted up or slanted down (from left to right)? How do
you know?

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?
