Final answer:
The question seems incomplete and lacks sufficient context to determine when a graph is negative. However, the concepts of negative and positive slopes and horizontal lines at negative values provide a basic understanding of conditions that can result in a graph being negative.
Step-by-step explanation:
The question "The graph is negative when..." likely refers to the values that a function or a specific part of a graph assumes below the x-axis, where y-values are negative. When discussing lines or curves on a graph, their 'negative' or 'positive' nature depends on the y-values they have in relation to the x-axis. Based on the provided options and relevant information, none appear to directly conclude when a graph is negative without additional context. However, given that options involve x being less than or greater than -3, we can infer that the subject graph changes at x = -3. If a graph is negative for values of x less than -3 and also for values greater than -3, there seems to be a contradiction unless there's a point of discontinuity or a piecewise function.
To provide a correct answer, more information is required, such as the function's equation or a visual representation of the graph. If we consider the general behavior of lines and the slope: negative slope indicates the line decreases as x increases, while positive slope means the line increases as x increases. A horizontal line at a negative value would be negative for all values of x since it's constant and below the x-axis. Based on this, one of the incomplete responses suggests a scenario where a horizontal line has a negative y-value, which would indeed mean the graph is negative at all points on that line.
In conclusion, without full context or additional options to choose from, we cannot definitively select one of the listed options as correct. However, the discussion related to slopes and horizontal lines provides a general understanding that could apply to various functions and their graphs.
