Work Step by Step
Graph a blank number line and label the intervals accordingly. In $x\geq-1$, $-1$ is a solution because it states that $x$ is greater than OR EQUAL TO $-1$, so when graphing the inequality, there needs to be a closed circle at the point $-1$. The numbers less than $-1$ are to the left of $-1$ on the number line, and the numbers greater than $-1$ are to the right of $-1$ on the number line. Because the inequality states that $x$ is greater than or equal to $-1$, we shade to the right of our point of $-1$. The graph we are left with matches answer choice B.
