# Line slope calculator 7x-3y=-3

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

## Calculation:

**Slope-intercept form of line:**y = 2.3333x+1

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

**Parametric form of the line equation:**

x = 3t

y = 7t+1 ; t ∈ R

**Slope:**m = 2.3333

**Slope angle of line: φ =**66°48'5″ = 1.1659 rad

**X intercept:**x

_{0}= -0.4286

**Y intercept:**y

_{0}= q = 1

**Distance line from the origin:**d

_{0}= 0.3939

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

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

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

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

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

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

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

**Scalar product OA .OB = 8**

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