x = 9t+1

y = 2t+1 ; t ∈ R

**Slope:**m = 0.2222

**Slope angle of line: φ =**12°31'44″ = 0.2187 rad

**X intercept:**x

_{0}= -3.5

**Y intercept:**y

_{0}= q = 0.7778

**Distance line from the origin:**d

_{0}= 0.7593

**The length of the segment AB: |AB| =**9.2195

**Vector: AB =**(9; 2)

**Normal vector: n =**(2; -9)

**Midpoint of the segment AB: M =**[5.5; 2]

**Perpendicular Bisector equation:**9x+2y-53.5 = 0

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

**Vector OB = (10; 3) ; |OB| = 10.4403**

**Scalar product OA .OB = 13**
