__Up and Down with Slopes Lesson Plan__

Using Microsoft Excel as well as traditional
methods, students will find the slope, x-intercept and
y-intercept of linear equations, graph linear
equations, discover the relationship between parallel
and perpendicular lines and graph parallel and
perpendicular lines. Using Microsoft Word, they will
write a report detailing their findings on parallel and
perpendicular lines.
