IM 8.3.11 Practice: Equations of All Kinds of Lines
Suppose you wanted to graph the equation y = -4x - 1
Describe the steps you would take to draw the graph.
How would you check that the graph you drew is correct?
Use the applet to answer the next set of problems:
Draw the following lines and then write an equation for each.
Slope is 0, -intercept is 5
Slope is 2, -intercept is -1
Slope is -2, -intercept is 1
Slope is , -intercept is -1
Write an equation for each line.
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. Bond paper has a thickness of inch per one hundred pages. Write an equation for the width of the book, , if it has hundred pages, printed on bond paper.
Ledger paper has a thickness of inch per one hundred pages. Write an equation for the width of the book, , if it has hundred pages, printed on ledger paper.
If they instead chose front and back covers of thickness of an inch, how would this change the equations in the previous two parts?
