x = 9t+1

y = 7t+1 ; t ∈ R

**Slope:**m = 0.7778

**Slope angle of line: φ =**37°52'30″ = 0.661 rad

**X intercept:**x

_{0}= -0.2857

**Y intercept:**y

_{0}= q = 0.2222

**Distance line from the origin:**d

_{0}= 0.1754

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

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

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

**Midpoint of the segment AB: M =**[5.5; 4.5]

**Perpendicular Bisector equation:**9x+7y-81 = 0

**Vector OA = (1; 1) ; |OA| = 1.4142**

**Vector OB = (10; 8) ; |OB| = 12.8062**

**Scalar product OA .OB = 18**
