Find the slope of the line that passes through (10, 9) and (5, 1).

Simplify your answer and write it as a proper fraction, improper fraction, or integer.

The slope of the line passing through the points (10, 9) and (5, 1) can be found using the formula:

m = (y2 - y1) / (x2 - x1)

Plugging in the values from the given points:

m = (1 - 9) / (5 - 10)
= (-8) / (-5)
= 8/5

Therefore, the slope of the line is 8/5.
