The slope is #-1#.

Explanation:

The formula for calculating slope from two points on a line is #m=(y_2-y_1)/(x_2-x_1)#, where #m# is the slope, #(x_1,y_1)# and #(x_2,y_2)# are the two points.

#(x_1,y_1)=(0,0)#

#(x_2,y_2)=(3,-3)#

Substitute the values for each point and solve for #m#.

#m=(y_2-y_1)/(x_2-x_1)=(-3-0)/(3-0)=#

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

The slope is #-1#.
