Find the slope of the line.

9x+y=9

Answer: - 9/1

Step-by-step explanation: you want to get x and y on opposite sides so you subtract 9x and that gives you y=-9x+9 because the nine on the right side doesn't have a negative in front of it so you know it's positive. Your slope is whatever comes before the x so since it's - 9 that means it's - 9/1
