What is the slope of the line passing through the points (4, 3) and (9, 2)?

1. -2

2. -1/2

3. 1/2

4. 2

The correct answer is: -1/2

The slope of a line can be calculated by finding the change in y divided by the change in x (rise over run). In this case, starting from the point (4, 3) and moving to the point (9, 2), we see that the change in y is -1 (3-2) and the change in x is 5 (9-4). Therefore, the slope is -1/5. Option A is incorrect because the slope cannot result in a negative number if the line is moving from left to right. Option C is incorrect because the slope of a line cannot be negative if the line is moving upwards from left to right. Option D is incorrect because the slope of a line cannot be a positive number if the line is moving downwards from left to right. The correct answer is B because it correctly shows the change in y as negative, indicating a downwards
