1. Day 13
Geometry

2. Warm Up
1) Write the equation of the line through the points (–1,3) and (5, –1) in point-slope form.
2) 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).
