# Line slope calculator 2x+9y=29

**Straight line given by points A[1; 3] and B[10; 1]**

## Calculation:

**Slope-intercept form of line:**y = -0.2222x+3.2222

**Canonical form of the line equation:**2x+9y-29 = 0

**Parametric form of the line equation:**

x = 9t+1

y = -2t+3 ; t ∈ R

**Slope:**m = -0.2222

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

**X intercept:**x

_{0}= 14.5

**Y intercept:**y

_{0}= q = 3.2222

**Distance line from the origin:**d

_{0}= 3.1455

**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-45.5 = 0

**Vector OA = (1; 3) ; |OA| = 3.1623**

**Vector OB = (10; 1) ; |OB| = 10.0499**

**Scalar product OA .OB = 13**

**Angle ∠ AOB = 65°51'16″ = 1.1494 rad**
