Question

Bryan is asked to write an inequality to represent the graph.

A number line going from negative 16 to negative 10. An open circle is at negative 14. Everything to the right of the circle is shaded.
He writes Negative 14 less-than-or-equal-to x.

Which error did Bryan make?
Bryan must write the inequality with the variable on the left side of the relation symbol.
Bryan chose a relation symbol that does not point in the same direction as the ray.
Bryan included –14 in his solution set.
Bryan used the wrong number in his inequality.

Answer 1

"Bryan included –14 in his solution set."

Explanation: the open circle at −14 means −14 is not included, so the correct inequality is x > −14. Bryan's −14 ≤ x (equivalently x ≥ −14) incorrectly includes −14.
