The slope of the line through the points #(-1,2)# and #(-5,1)# is #1/4#.

Use the slope formula:

#m=(y_2-y_1)/(x_2-x_1)#

A point can be written like this:

#P_a=(x_a, y_a)#

So our two points are:

#P_1=(-1,2)#
and
#P_2=(-5,1)#

Now plug in out values to the slope formula:

#m=(y_2-y_1)/(x_2-x_1)#

#color(white)m=(1-2)/(-5-(-1))#

#color(white)m=(-1)/(-5+1)#

#color(white)m=(-1)/(-4)#

#color(white)m=1/4#

The slope of the line is #1/4#.
