# Line slope calculator x-2y=-1

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

## Calculation:

**Slope:**m = 0.5

**Slope-intercept form of line:**y = 0.5x+0.5

**Canonical form of the line equation:**x-2y+1 = 0

**Parametric form of the line equation:**

x = 2t+1

y = t+1 ; t ∈ R

**Slope angle of line: φ =**26°33'54″ = 0.4636 rad

**X intercept:**x

_{0}= -1

**Y intercept:**y

_{0}= q = 0.5

**Distance line from the origin:**d

_{0}= 0.4472

**The length of the segment AB: |AB| =**2.2361

**Vector: AB =**(2; 1)

**Normal vector: n =**(1; -2)

**Midpoint of the segment AB: M =**[2; 1.5]

**Perpendicular Bisector equation:**2x+y-5.5 = 0

**Vector OA = (1; 1) ; |OA| = 1.4142**

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

**Scalar product OA .OB = 5**

**Angle ∠ AOB = 11°18'36″ = 0.1974 rad**
