Answer:
The slope of the line passing through two points (8,10) and (3,9) is 1/5.
The slope of a line passing through two points can be calculated using the formula:

In this case, the points are (8,10) and (3,9). Let's calculate the slope:



So, the slope of the line passing through two points (8,10) and (3,9) is 1/5.
