1. 1-5 Writing Equations of Parallel and Perpendicular Lines
Pre Calc A

2. Vocabulary
Parallel
Perpendicular
Coincide

3. Ex 17:
Determine whether the graphs of each pair of equations are parallel, perpendicular, or neither.
2x + 4y = 4 and x + 2y = 5
6x + y = -2 and –x + 6y = 8
y = 2x – 8 and 4x – 2y = 16

4. Ex :
Write the standard form of the equation of the line that passes through the point (-2, 10) and is parallel to the graph 2x + 5y = -4

5. Ex last one:
Write an equation in standard form of the line that passes through (2, -3) and is perpendicular to 6x – 8y = 5
