Suppose a line graphed on a coordinate plane represents the distance traveled in miles by an automobile as a function of time in hours. Assuming that the relationship between time and distance traveled is proportional, which of these statements is correct? A If the automobile was going 25 mph, the slope of the line is −1/25.

B If the automobile was going 40 mph, the y-intercept of the line is −1/40.

C If the automobile was going 45 mph, the y-intercept of the line is 1/45.

D If the automobile was going 50 mph, the slope of the line is 50.

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?

The measure of angle 0 is 600 degrees
