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

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 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 correct response is:
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 indicates that the student misunderstood the inequality direction and associated the wrong graph representation with the given inequality \( -4 < x \). The correct graph should show that x is greater than -4, which would be represented with an open circle at -4 and a line extending to the right.
