Final answer:
The slope of a line cannot be determined with only a single point listed; two points are required to calculate the slope, which is the rise over the run.
The correct answer is: D) − 2/1
Step-by-step explanation:
Given a single point, it is not possible to determine the slope of a line just from that information. The slope of a line is the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line. Without a second point, there is no change to measure and therefore no slope to calculate.
The slope of a line cannot be determined with only a single point listed; two points are required to calculate the slope, which is the rise over the run.
The provided options (1/2, -1, 2, -2) could all be slopes of different lines that pass through the point (0,-2), but additional information, such as a second point or the equation of the line, is needed to determine the negative slope of the line in question.
