Intermediate Algebra
Parallel & Perpendicular Lines

Homework:

Write an equation in slope-intercept form for the line that contains point (6, -5) and is
  • parallel to the line 2x -5y = -3
  • perpendicular to the line 2x + 5y = 3

Assignments:
  • Do Now
  • Focus Questions
  • Exploring Parallel & Perpendicular Lines
  • Notes
  • Practice Problems
Today's Do Now:

1. Tina leaves home and drives at a constant speed to college. On her way to the campus, she stops at a restaurant to have lunch. Two hours after leaving the restaurant, Tina has traveled 130 miles, and 4 hours after leaving the restaurant, she has traveled 240 miles. How far from home was Tina when she had lunch?

Today's Focus Questions:

1. Describe how to determine whether the lines 5x + 6y = 12 and 6x – 5y =15 are parallel, perpendicular, or neither.
2. Explain how to write the equation for the line that contains the point (3, -1) and is perpendicular to the line x + 2y = 4
