Find the equation of the perpendicular bisector of the line segment joining A (2, 5) and B (4, 3).
x – y + 1 = 0
y – x + 2 = 0
x – y + 6 = 2
y – x + 3 = 1
The equation of the line parallel to the line 2x – 3y = 1 and passing through the middle point of the line segment joining the points (1, 3) and (1, –7), is:
