1. Write down the equation of a line perpendicular to y = 4x + 6
2. Write down the equation of a line perpendicular to y = 4x + 6 which passes through (0, -4)
3. Find the equation of a line perpendicular to 4y - 2x + 8 = 0
4. Find the equation of a line perpendicular to y = -43x - 6 which passes through (0, 3)
5. Find the equation of a line perpendicular to 2y - 3x + 5 = 0 which passes through (0, -4)
6. Line A passes through the points (4,3) and (8,6). Find the equation of the line perpendicular to line A that passes through (6,12)
7. Line A passes through the points (1,1) and (4,7)
Line B passes through the points (7,4) and (11,6)
Determine whether Line A and line B are perpendicular.
8. Line A passes through the points (-5,-1) and (-1,11)
