Given the system of straight line a(2x + y – 3) + b(3x + 2y – 5) = 0, the line of the system farthest form the point (4, –3) has the equation
The given system of lines pass through (1, 1)
So, the required line is the through (1, 1) and perpendicular
to the join of (1, 1) and (4, –3).
The equation of line is
