What is the slope and y-intercept of the line x + y + 2 = 0?
slope = -1
intercept = -2
The standard equation of the line in the slope-intercept form is
So our work is to get the equation in this particular form.
This is an equation in the slope-intercept form, and we can compare it with the equation
(Try and draw a graph, and it would be very clear to you what the negative slope and intercept means.)
