Standards:

• Common Core
  • HSG.GPE.B.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).
• TEKS
  • A.2(E) – write the equation of a line that contains a given point and is parallel to a given line
  • A.2(F) – write the equation of a line that contains a given point and is perpendicular to a given line
