Step 3: Slope is Rise/Run. -3 divided by 1 is just -3 so we can simplify the answer. Double check the sign of your answer. The line is going down to the right, so the slope should be negative.
Be extra careful when the line goes down to the right. A common mistake is to make both the rise and the run negative.
