1. Day 13 Geometry

2. Warm Up  Write the equation of the line through the points (– 1,3) and (5, –1) in point-slope form.  Graph the line –6x + 7y = –84 using the x– and the y– intercepts.

3. Homework Check

4. Learning Objective 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).
