# Line slope calculator x+9y=46

**Straight line given by points A[1; 5] and B[10; 4]**

## Calculation:

**Slope-intercept form of line:**y = -0.1111x+5.1111

**Canonical form of the line equation:**x+9y-46 = 0

**Parametric form of the line equation:**

x = 9t+1

y = -t+5 ; t ∈ R

**Slope:**m = -0.1111

**Slope angle of line: φ =**-6°20'25″ = -0.1107 rad

**X intercept:**x

_{0}= 46

**Y intercept:**y

_{0}= q = 5.1111

**Distance line from the origin:**d

_{0}= 5.0799

**The length of the segment AB: |AB| =**9.0554

**Vector: AB =**(9; -1)

**Normal vector: n =**(1; 9)

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

**Perpendicular Bisector equation:**9x-y-45 = 0

**Vector OA = (1; 5) ; |OA| = 5.099**

**Vector OB = (10; 4) ; |OB| = 10.7703**

**Scalar product OA .OB = 30**

**Angle ∠ AOB = 56°53'19″ = 0.9929 rad**
