**X intercept:**x

_{0}= 2.2222

**Y intercept:**y

_{0}= q = -2.8571

**Distance line from the origin:**d

_{0}= 1.7541

**The length of the segment AB: |AB| =**11.4018

**Vector: AB =**(7; 9)

**Normal vector: n =**(9; -7)

**Midpoint of the segment AB: M =**[6.5; 5.5]

**Perpendicular Bisector equation:**7x+9y-95 = 0

**Vector OA = (3; 1) ; |OA| = 3.1623**

**Vector OB = (10; 10) ; |OB| = 14.1421**

**Scalar product OA .OB = 40**
