The student should have multiplied by a negative and switched the direction of the arrow on the graph to go right instead of left

The student did not make a mistake; this is the correct graph of the inequality
The student did not make a mistake; this is the correct graph of the inequality

The student did x is less than -4, when the variable is on the other side; -4 is less than x so x is greater than -4
The student did x is less than -4, when the variable is on the other side; -4 is less than x so x is greater than -4

The student should have filled in the point at -4 to show the solution x could be equal to -4

Based on the provided responses, the most accurate description of the student's mistake would be this option:

"The student did x is less than -4, when the variable is on the other side; -4 is less than x so x is greater than -4."

This option indicates that the student misinterpreted the inequality, switching the inequality sign unintentionally. The other options either misidentify the correctness of the graph or address a different aspect of the inequality.
