You started with a rope that is 40 feet long, and you plan to tie a series of knots along the rope. As you tie knots, you notice that the overall length of the rope decreases by 0.29 feet per knot. Let x represent the number of knots in the rope and y represent the length (in feet) of the rope.

Create a table of values that reflects this situation.

x y

Write an equation that models this situation. Use x and y (as defined above) as your variables.
