Algebra-1

To determine which graph represents “x is at least 1”, we need to understand what this inequality means and how it is represented on a number line.

 

“x is at least 1” can be represented as x ≥ 1 means that x includes 1 and all numbers greater than 1. On a number line, this is represented by: A line with a closed circle at 1 and shading to the right.

 

To compare the given graphs:

Graph A

There is an open circle at 1 and the shading extends to the right.

This represents x > 1, as it includes all numbers greater than 1 but not 1 itself.

 

Graph B

There is a closed circle at 1 and the...
