First observe the line. The slope will be negative because the line is going up to the left. When figuring out the slope, pick two points. I am going to pick (-2,0) and (-3,1). Use the rise over run method. When starting at (-2,0), go up and over until you reach (-3,1). That means you have to go 1 up and 1 over. 1/1 is 1. The line is negative, so 1 will turn into -1. I hope this helps! Let me know if you have any questions or if this is wrong.
