They are vectors of equal magnitudes in oppositedirections. When you add them, they cancel out each other.

A unit vector is a vector whose magnitude is one. Vectors can have magnitudes that are bigger or smaller than one so they would not be unit vectors.
yeah, it can. for example consider two antiparallel vectors of magnitude 5,3 whose resultant is 2, which is smaller than both components.....
Two is the minimum number of vectors that will sum to zero.

-- A singe vector with a magnitude of zero produces a zero resultant.-- Two vectors with equal magnitudes and opposite directions produce a zero resultant.

In addition of vector when vector A whose head is joined to the tail of the vector B and then the tail of the vector A is linked with the tail of the resultant vector and the head of the vector B is joined with the head of the resultant vector..... it means the addition of vectors are also defined the head to tail rule..
|v| = vx|v| = Sqrt(vx2 + vy2)|v| = Sqrt(vx2 + vy2 + vz2)
Start with a point O. Draw a line OA in the direction of the first vector and whose length represents the magnitude of that vector (to some scale). From A, draw the line AB in the direction of the second vector and whose length represents the magnitude of that second vector (to the same scale). Then the direction and length of the straight line OB represent the direction and (to the same scale) the magnitude of the resultant vector.
You can do it graphically by drawing the vectors with the end of the first touching the beginning of the second, the end of the second touching the beginning of the third, and so on, being careful to maintain the direction and the scale of the magnitude of each. The resultant is then the vector that starts at the beginning of the first vector and ends at the end of the last vector. You should get the same resultant no matter what order you put the vectors in. You can do it matematically by trigonometrically separating each vector into its x and y components, adding together all the x's and adding together all the y's, then calculating the resultant. Think of each vector as the hypotenuse of a right triangle. After adding together the x's and y's, the two sums are the two sides of a right triangle whose hypotenuse is the resultant.

Vectors are often represented by arrows whose length is proportional to the magnitude of the vector. The arrowhead points to the direction the vector is acting. You'll have to decide if such an arrow fits your definition of a line.
