The number of points in space, whose each co-ordinate is a negative integer such that `x +y+z+ 12= 0`

Number of points having positive intergal co - ordinate lying on the plane x+2y+3z = 15 is n, then n/2 is equal to

If x is positive even integer and y is negative odd integer, then x^(y) is

The polar co-ordinates of the point whose cartesian co-ordinates are (-1,-1) is :

The co-ordinates of a point on 2y ^(2) =7x whose parameter is -2 are

The polar co-ordinates of the point whose cartesian co-ordinates are (5, 0) , are

The number 3,4,5 can be (A) direction cosines of a line in space (B) direction numbers of a line in space (C) coordinates of a point on the line y=4z=0 (D) coordinates of a point in the plane x+y-z=0

The length of the intercepts on the co-ordinate axes made by the plane 5x + 2y + z - 13 = 0 are
