The slope, #m#, is #3#.

Explanation:

The equation for finding the slope of a line from two points is #m=(y_2-y_1)/(x_2,x_1)#, where #m# is the slope, #(x_1,y_1)# is on point and #(x_2,y_2)# is the other point.

Point 1:#(-3,-1)#
Point 2:#(-1,5)#

Substitute the values for the points into the equation.

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

#m=(5-(-1))/(-1-(-3))#

Simplify.

#m=(5+1)/(-1+3)#

Simplify.

#m=6/2#

Simplify.

#m=3#
