# Line slope calculator x+9y=54

**Straight line given by points A[0; 6] and B[9; 5]**

## Calculation:

**Slope-intercept form of line:**y = -0.1111x+6

**Canonical form of the line equation:**x+9y-54 = 0

**Parametric form of the line equation:**

x = 9t

y = -t+6 ; t ∈ R

**Slope:**m = -0.1111

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

**X intercept:**x

_{0}= 54

**Y intercept:**y

_{0}= q = 6

**Distance line from the origin:**d

_{0}= 5.9633

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

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

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

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

**Perpendicular Bisector equation:**9x-y-35 = 0

**Vector OA = (0; 6) ; |OA| = 6**

**Vector OB = (9; 5) ; |OB| = 10.2956**

**Scalar product OA .OB = 30**

**Angle ∠ AOB = 60°56'43″ = 1.0637 rad**
