Question

Which of the following inequalities matches the graph? graph of an inequality with a solid horizontal line through the point 0, negative 1 and shading above the line

Answer 1

`y\geq -1`

Explanation:

The inequality has the attached picture as its graph.. The inequality passes through (0,-1) and is a horizontal line. This means the inequality has the form y < b or y > b where b is the y-coordinate. Since the \shading is above the line then the values must be greater than -1. It is also a solid line so the inequality is equal to. The inequality is
`y\geq -1`
