If ` 3a + 2b + 6c = 0 ` the family of straight lines `ax+by + c = 0 ` passes through a fixed point . Find the coordinates of fixed point .

If a, b, c are in A. P., then st. line ax+by+c=0 will always pass through a fixed point whose co-ordinates are:

If the straight line ax +by+c=0 always passes through (1,-2) then a,b,c are in

If 4a^2 + 9b^2 - c^2 + 12ab =0 , then the family of straight lines ax + by + c =0 is concurrent at

If the straight line ax + by + c =0 always passes thorugh ( 1, - 2) , then a,b,c, are in :

A straight line which passes through two points on a circle is

If the straight line ax+by+c=0 always passes through (1, -2), then a, b, c are in:

If non-zero numbers a, b, c are in H.P., then the straight line (x)/(a)+(y)/(b)+(1)/(c )=0 always passes through a fixed point. That point is :

Aray of light passing through the point (1, 2) reflects on the x-axis at point and the reflected ray passes through the point (5,3). Find the coordinates of A.
