1. • The length of a rope is measured and recorded in the following table. Knots were tied in the rope, one at a time. After each knot was added, the length of the rope was measured and recorded. A total of five knots were tied.

Number of knots	0	1	2	3	4	5
Length of rope (cm)	100	92	84	76	68	60

1. • 1. 1 What is the independent variable in this situation? What is the dependent variable? Explain.
     2. 3 2 What is the domain of the situation? What is the range of the situation?
     3. Create a scatterplot of the length l of the rope versus the number of knots n tied in the rope. Describe your graph.
     4. 4 What are the coordinates of the l-intercept in this situation?
     5. 5 In symbolic form, this function can be represented as l=−8n+100l=−8n+100. Use this equation to predict the length of the rope when 11 knots are tied in it.
