Question

If the algebraic sum of the perpendicular distances from the point (2,0), (0,2) and (1, 1) to a variable straight line be zero, then the line passes through the point

(a) (3, 3)

(b) (1, 1)

(c) (1, -1)

(d) (-1, -1)

Answer 1

Correct option is (b) (1, 1)

Let equation be ax + by + c = 0

This shows that ax + by + c = 0 passes through (1, 1).
