Find the slope of the line passing through the points 6,-1 and 4,-5 .

The slope of a line passing through two points (x1, y1) and (x2, y2) can be found using the formula:

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

In this case, the points are (6, -1) and (4, -5):

m = (-5 - (-1)) / (4 - 6)
= (-5 + 1) / (-2)
= -4 / -2
= 2

Therefore, the slope of the line passing through the points 6, -1 and 4, -5 is 2.
