I added a picture : Determine which of the lines, if any, are parallel or perpendicular. Explain. write an equation of the line that passes through the given point and is perpendicular to the given line.

1. line a and c and parallel. line b is perpendicular with line a and c. 2. line b and c and parallel. line a is perpendicular to lines b and c. 3. y= -3x + 3 4. y=(5/3)x - 9

Step-by-step explanation:

To find parallel and perpendicular, make the slope opposite and find b by plugging in the points. Parallel is the same slope.
