Write an equation of the line that passes through the given point and is (a) parallel and (b) perpendicular to the given line. A line and a dot are graphed on a coordinate plane. The x-axis ranges from negative 1 to 7, in increments of 1. The y-axis ranges from negative 5 to 3, in increments of 1. The line passes through the points at ordered pair 0 comma negative 4 and ordered pair 2 comma 2. A dot is at ordered pair 6 comma 2.

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?

If sin(x) = 0 and cos(x) = 1, what is tan(x)?
