slope = -1
intercept = -2

Explanation:

The standard equation of the line in the slope-intercept form is #y = mx+c#, where #m# is the slope and #c# is the intercept.

So our work is to get the equation in this particular form.

# x + y + 2 = 0 #
# => y = -x - 2 #
# => y = (-1) x + (-2) #
This is an equation in the slope-intercept form, and we can compare it with the equation #y = mx+c# to get # m = -1 # and # c = -2 #.

(Try and draw a graph, and it would be very clear to you what the negative slope and intercept means.)
