Question

Which of the following represents the number line of $\text{x}$, where $\text{x}$ is at least -2?

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

Given, $x$ is a number that is at least -2 which means the minimum value of the number $x$ is $-2$

Hence, $x$ can have any value which is less than or equal to $-2$ and closed circle will be on -2.
Arrow of the line will be towards right side as x is greater than -2.

Representing the above expression in mathematical inequality:
$x\ge -2$
