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 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 a line parallel or perpendicular to the given line.


Introduction/Connection (Bellringer): Students will complete #1-9 on Practice Worksheet Writing Linear Equations (attached below)


Direct Instruction/Guided Practice:
--Review bellringer
--Review classwork from Tuesday (writing Equations of Lines giving slope, point and two points)
--Finish foldable on writing equations of lines
--Guide students in identifying parallel and perpendicular slopes.


Independent Practice/Collaboration/Differentiation:
--Differentiation: Graphic organizers and foldables, one-on-one assistance for students needing help, provide more rigor for accelerated learners.


Resources: DeltaMath and IXL


Assignment: Students will complete:
1) DeltaMath: Finding Slope
2) IXL:
--E2 Slopes of Lines (shortcut V2T)
--E5 Slopes of Parallel and Perpendicular Lines (shortcut 6K2)
