1. Tell whether the lines are "parallel", "perpendicular", or "neither."
9x + 3y = 12
12x + 4y = 18

2. Write an equation of the line described.
Through (7, 1), parallel to -8x + 7y = -28

3. Do you prefer to use the method of plotting points or the method using the intercepts to graph an equation? y=2/3x-27? why
