Standards Addressed:
MGSE.9-12.G.GPE.5 Prove the slope criteria for parallel and perpendicular lines and use them to solve geometric problems (e.g. find the equation of a line parallel or perpendicular to a given line that passes through a given point).

Learning Targets /Success Criteria I can solve problems involving parallel and perpendicular lines.
• I can identify lines that are parallel or perpendicular.
• I can apply the properties of parallel and perpendicular lines
• I can identify the slope of a line given a graph, two points or an equation of a line.
• I can determine the slope intercept form of the equation of a line given: standard form, the slope and a point on the line, two points and a line parallel or perpendicular to the given line.


Introduction/Connection (Bellringer): students will complete back of Lunch lines task.


Direct Instruction/Guided Practice:
--review bellringer
--review slope with #1 a-d on Parallel + Perpendicular Lines (attached below).
--Guide students in reviewing writing equations of lines given various information (slope & y intercept, two points, point and slope, and graph) using foldable (attached below)
