Which set dose - 4/9 belong A integers B whole numbers C natural numbers D rational numbers

-4/9 is a rational number

Step-by-step explanation:

Rational numbers are the numbers you can make by dividing one integer by another, so in other words a fraction.

Answer

4/9 belongs to rational numbers (D).

Explanation

(Lol moderator deleted everyone's answers so I'm gonna answer).

First I'll give you a definition of each choice.

Integers: Integers don't include decimals or fractions. Integers are positive and negative numbers. So basically it's this; (..., -3, -2, -1, 0, 1, 2, 3, ...). The '...' means numbers from infinity to the next number. I hope this makes sense Imao.

Whole numbers: whole numbers are integers, except they don't include negative numbers. Whole numbers include 0 (zero)... (0, 1, 2, 3, ...)

Natural numbers: natural numbers are whole numbers but they don't include 0 (zero)... (1, 2, 3, ...)

Rational numbers: rational numbers are numbers that can be expressed as a fraction. This includes repeating decimals such as 0.333 repeating. Rational numbers also include integers, because if you put the number over one, that is a fraction. Rational numbers are basically every number except for the radicals of some numbers (such as the square root of 3) and pi.

So now let's just see which one 4/9 is.

Well, 4/9 is not an integer, whole number, or natural number because it is a fraction.

But 4/9 can be expressed as a fraction (well, it already is one) meaning it is a rational number.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
