Answer 1

see below

Explanation:

When you see "(variable) < " or "(variable) ≤ ", you should be looking for a line that extends to the left along the number line. The right end of the number line will be at the constant in this inequality. Here, the right end is -1. The circle is solid because the value -1 is included in the solution set.

The appropriate choice is the one shown below.
