Review what you know about graphs by answering the following questions.

  1. A 4 quadrant coordinate graph with a line going through the points (negative 1, comma 3) and (1, negative comma 1).Find the equation of the line graphed above.

    Use the ntercept and the growth rate to write the equation of the line at right.

  2. What are its and intercepts?

    Remember that the intercept is the point on the graph where and that the intercept is the point where .

  3. On your own graph paper, graph the line.

  4. On the same set of axes, graph a line parallel to the line graphed at right, but through the origin . Find the equation of this new line.

    Remember that parallel lines have the exact same growth rate.

    Plug in the point given into the basic equation and simplify to find the equation of the line.
