Work Step by Step

Graph a blank number line and label the intervals accordingly. In $-1\lt x$, $-1$ is not a solution, so when graphing the inequality, there needs to be an open 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 $-1$ is less than $x$, we shade to the right of our point of $-1$. The graph we are left with matches answer choice A.
