The slope is =1/2

Explanation:

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
