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

These questions usually are formatted in this way

(-2,-1) and (2,-6) is #(x_1, y_1)# and #(x_2, y_2)#

#x_1=-2#
#x_2=2#

#y_1=-1#
#y_2=-6#

#y_2-y_1=(-6-(-1))=-5#
#x_2-x_1=(2-(-2))=4#

slope = #(y_2-y_1)/(x_2-x_1)=(-6-(-1))/(2-(-2))=#-5/4#=-1.25#

The slope of (-2,-1) and (2,-6) can be represented as a decimal, fraction, or percentage.

Slope as a decimal

= #-1.25#

a fraction

= #-5/4#

and a percentage

= #-1.25xx100%=-125%#
