# Line slope calculator 3x-7y=3

**Straight line given by points A[1; 0] and B[8; 3]**

## Calculation:

**Slope-intercept form of line:**y = 0.4286x-0.4286

**Canonical form of the line equation:**3x-7y-3 = 0

**Parametric form of the line equation:**

x = 7t+1

y = 3t ; t ∈ R

**Slope:**m = 0.4286

**Slope angle of line: φ =**23°11'55″ = 0.4049 rad

**X intercept:**x

_{0}= 1

**Y intercept:**y

_{0}= q = -0.4286

**Distance line from the origin:**d

_{0}= 0.3939

**The length of the segment AB: |AB| =**7.6158

**Vector: AB =**(7; 3)

**Normal vector: n =**(3; -7)

**Midpoint of the segment AB: M =**[4.5; 1.5]

**Perpendicular Bisector equation:**7x+3y-36 = 0

**Vector OA = (1; 0) ; |OA| = 1**

**Vector OB = (8; 3) ; |OB| = 8.544**

**Scalar product OA .OB = 8**

**Angle ∠ AOB = 20°33'22″ = 0.3588 rad**
