Answer:

Option A) The sum of x and y is a rational number

Step-by-step explanation:

we know that

A rational number is a number that can be written as a ratio or quotient of two integers

so

In this problem we have

[tex]x=-5, y=-4[/tex]

[tex]x+y=-5-4=-9[/tex]

Is a rational number, because the number [tex]-9[/tex] can be written as a ratio or quotient of two integers

Example

[tex]-\frac{27}{3}=-9[/tex]

[tex]-\frac{9}{1}=-9[/tex]
