Answer 1

Inequalities can be represented on graphs, and vice versa.

The required graphs are missing; so, I will give a general guide on how to determine an inequality from a graph.

See attachment for graphs to be used for illustration

Graph 1

Check the circle type

The circle on the graph is a closed circle:

This means that the inequality will either use a greater or equal to sign or a less than or equal to sign

Check the arrow direction

The arrow on the graph points to the left; this indicates less than.

So, the inequality will use a less than or equal to sign

Check the numbers

The circle stops at 11

When the above analysis are combined, the inequality would be $x \le 11$

Graph 2

Check the circle type

The circle on the graph is an open circle:

This means that the inequality will either use a greater than sign or a less than sign

Check the arrow direction

The arrow on the graph points to the right; this indicates greater than.

So, the inequality will use a greater than sign

Check the numbers

The circle stops at 11

When the above analysis are combined, the inequality would be $x > 11$
