Question

1. $nleq - 1$

Explanation:

Step1: Identify the inequality

The inequality is $n\leq - 1$.

Step2: Graph on number - line

We mark a closed circle at $-1$ (because the inequality includes equality, i.e., $\leq$) and shade the line to the left of $-1$ as all values of $n$ that are less than or equal to $-1$ satisfy the inequality.

Answer:

The graph of the inequality $n\leq - 1$ has a closed - circle at $-1$ and the line is shaded to the left of $-1$ on the number - line.
