**Parametric form of the line equation:**

x = 4t+1

y = 2t+8 ; t ∈ R

**Slope:**m = 0.5

**Slope angle of line: φ =**26°33'54″ = 0.4636 rad

**X intercept:**x

_{0}= -15

**Y intercept:**y

_{0}= q = 7.5

**Distance line from the origin:**d

_{0}= 6.7082

**The length of the segment AB: |AB| =**4.4721

**Vector: AB =**(4; 2)

**Normal vector: n =**(2; -4)

**Midpoint of the segment AB: M =**[3; 9]

**Perpendicular Bisector equation:**4x+2y-30 = 0

**Vector OA = (1; 8) ; |OA| = 8.0623**

**Vector OB = (5; 10) ; |OB| = 11.1803**

**Scalar product OA .OB = 85**

**Angle ∠ AOB = 19°26'24″ = 0.3393 rad**
