Final answer:
A negative slope on a graph indicates a negative relationship between two variables, such as between sales revenue and customer satisfaction. If a line representing this relationship has a negative slope, it means customer satisfaction decreases as sales revenue increases. To validate the correct statement, we must know if the line describing their relationship has a negative slope.
Step-by-step explanation:
When analyzing the given statements in relation to the provided descriptions of line slopes and their meanings, we can deduce the correlation between two variables based on the slope of a line in a graph. A negative slope indicates a negative relationship, meaning if one variable increases, the other decreases, and vice versa. Therefore, if the student's question concerns customer satisfaction and sales revenue, and we have a line that represents this relationship with a negative slope, it would suggest that as sales revenue increases, customer satisfaction decreases, or as sales revenue decreases, customer satisfaction increases. Given the information that a negative slope means two variables are negatively related, the true statement among the options provided would likely be 'customer satisfaction is declining ever more rapidly as the company’s sales revenue increases' if the context implies that customer satisfaction and sales revenue are represented by a line with a negative slope. To confirm which statement is true, we would need to determine whether the relationship they describe follows a line with a negative slope on a graph.
