Suppose you wanted to graph the equation . Describe the steps you would take to draw the graph.

Draw and label a line for each given slope and -intercept.

1. Line : slope is 0, -intercept is 5
2. Line : slope is 2, -intercept is -1
3. Line : slope is -2, -intercept is 1
4. Line : slope is , -intercept is -1

Write an equation for each line.

4 lines on coordinate grid colored red, blue, green, yellow. red line, y intercept = 4, slope =0. green line, x intercept = -1, no slope. blue line, y intercept = -2, slope = 0. yellow line, x intercept = 6, no slope 

A publisher wants to figure out how thick their new book will be. The book has a front cover and a back cover, each of which have a thickness of of an inch. They have a choice of which type of paper to print the book on.

1. Bond paper has a thickness of inch per one hundred pages. Write an equation for the total thickness of the book in inches, , if it has hundred pages, printed on bond paper.
2. Ledger paper has a thickness of inch per one hundred pages. Write an equation for the total thickness of the book in inches, , if it has hundred pages, printed on ledger paper.
3. If they instead chose front and back covers of thickness of an inch, how would this change the equations in the previous two parts?
