The slope is #=1/2#

The coordinates are:
#(-1,1) = color(blue)(x_1,y_1#

#(-3,0) = color(blue)(x_2,y_2#

The slope is calculated using formula:

slope #=color(green)( (y_2-y_1) / (x_2 - x_1)#
(ie; change in #y# axis divided by change in #x# axis)

# = (0-1) / (-3- (-1))#

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

# = (-1) / (-2)#

#=1/2#
