What is an equation in point-slope form of the line that passes through the point (8, 5) and has slope −7? A. y + 5 = 7(x + 8)
B. y + 5 = −7(x + 8)
C. y − 5 = 7(x − 8)
D. y − 5 = −7(x − 8)

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?
