# Line slope calculator 3x-y=3

**Straight line given by points A[1; 0] and B[2; 3]**

## Calculation:

**Slope-intercept form of line:**y = 3x-3

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

**Parametric form of the line equation:**

x = t+1

y = 3t ; t ∈ R

**Slope:**m = 3

**Slope angle of line: φ =**71°33'54″ = 1.249 rad

**X intercept:**x

_{0}= 1

**Y intercept:**y

_{0}= q = -3

**Distance line from the origin:**d

_{0}= 0.9487

**The length of the segment AB: |AB| =**3.1623

**Vector: AB =**(1; 3)

**Normal vector: n =**(3; -1)

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

**Perpendicular Bisector equation:**x+3y-6 = 0

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

**Vector OB = (2; 3) ; |OB| = 3.6056**

**Scalar product OA .OB = 2**

**Angle ∠ AOB = 56°18'36″ = 0.9828 rad**
