If a,b and c are in AP, then the straight lines `ax+by +c=0` will always pass through.........

If a , b and c are in A P , then the straight line a x+b y+c=0 will always pass through a fixed point whose coordinates are______

If a , b and c are in A P , then the straight line a x+b y+c=0 will always pass through a fixed point whose coordinates are (a) (1,2) (b) (1,-2) (c) (2,3) (d) (0,0)

If a , b , c are in A.P ., then the equation 2ax+by +3c = 0 always passes through

If the vectors 2ahati+bhatj+chatk, bhati+chatj+2ahatk and chati+2ahatj+bhatk are coplanar vectors, then the straight lines ax+by+c=0 will always pass through the point

If a, c, b are in G.P then the line ax + by + c= 0

If a, b, c are in A.P then the lines represented by ax + by+ c= 0 are

If a , b ,c are in harmonic progression, then the straight line ((x/a))+(y/b)+(l/c)=0 always passes through a fixed point. Find that point.

If a + 2b + 3c = 0 " then " a/3+(2b)/3+c=0 and comparing with line ax + by + c, we get x = 1/3 & y = 2/ 3 so there will be a point (1/3,2/3) from where each of the lines of the form ax + by + c = 0 will pass for the given relation between a,b,c . We can say if there exists a linear relation between a,b,c then the family of straight lines of the form of ax + by +c pass through a fixed point . If a , b, c are consecutive odd integers then the line ax + by + c = 0 will pass through

If a, b, c are in A.P. then the family of lines ax+by+c=0 (A) passes through a fixed point (B) cuts equal intercepts on both the axes (C) forms a triangle with the axes with area = 1/2 |a+c -2b| (D) none of these

If a ,\ b , c are in A.P., then the line a x+b y+c=0 passes through a fixed point. write the coordinates of that point.
