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

Find the equation of the line graphed above. Use the

ntercept and the growth rate to write the equation of the line at right.What are its

andintercepts?Remember that the

intercept is the point on the graph whereand that theintercept is the point where.On your own graph paper, graph the line.

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.
