Question

According to the Ruler Postulate, what does the set of points on any line correspond to?

A: real numbers
B: natural numbers
C: rational numbers
D: irrational numbers

Answer 1

The correct answer is A) real numbers.

According to the Ruler Postulate, the set of points on any line correspond to real numbers.

The ruler postulate establishes that the points in a line can be paired with numbers that are real. It is the absolute value of the difference between the numbers that represent the distance between two points. So in simple terms, the ruler postulate allows mathematicians to know the distance of two separated points.

Answer 2

In a number line, the numbers on the right hand side of zero are all positive numbers (1, 2, 3, 4, ...). On the left hand side of zero are all negative numbers (-1, -2, -3, -4, ...). The numbers in the coordinates of the number line are all real numbers. Thus, the answer is letter A.
