y = 4t ; t ∈ R

**Slope:**m = 0.4444

**Slope angle of line: φ =**23°57'45″ = 0.4182 rad

**X intercept:**x

_{0}= 0

**Y intercept:**y

_{0}= q = 0

**Distance line from the origin:**d

_{0}= 0

**The length of the segment AB: |AB| =**9.8489

**Vector: AB =**(9; 4)

**Normal vector: n =**(4; -9)

**Midpoint of the segment AB: M =**[4.5; 2]

**Perpendicular Bisector equation:**9x+4y-48.5 = 0

**Vector OA = (0; 0) ; |OA| = 0**

**Vector OB = (9; 4) ; |OB| = 9.8489**

**Scalar product OA .OB = 0**

**Angle ∠ AOB = N/A = N/A rad**
