  1. Find the - and -intercepts for each equation.

    The -intercepts are and , and the -intercepts are and .

  2. Shade the region bounded by the two lines and the -axis.

  3. What are the domain and range of the region? How did you find these values?

    Look at the graph or the -intercepts to find the domain. Find the point of intersection to determine the range.

    The domain is , and the range is .

  4. Find the area of this region. Round your answer to the nearest tenth.
