Essential Question: How does the equation of a line relate to geometric terms and properties?

OAS Standard(s) Covered: G.2D.1.6 Use coordinate geometry and algebraic reasoning to represent and analyze line segments and polygons, including determining lengths, midpoints, and slopes of line segments.

Informal Knowledge Check Post-Lesson: What do m and b stand for in y=mx+b? What is another way to think of slope?

Informal Knowledge Check Post-Lesson: What is the relationship between slopes of parallel lines? What about slopes of perpendicular lines?

Informal Knowledge Check Post-Lesson: How does the midpoint relate to the perpendicular bisector?

Informal Knowledge Check Post-Lesson: What does the angle bisector tell us about the parts of a whole angle?

Informal Knowledge Check Post-Lesson: If the perpendicular bisector forms two triangles, what do you know about the longest legs of the triangles?
