# Line slope calculator x+2y=4

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

## Calculation:

**Slope-intercept form of line:**y = -0.5x+2

**Canonical form of the line equation:**x+2y-4 = 0

**Parametric form of the line equation:**

x = 2t

y = -t+2 ; t ∈ R

**Slope:**m = -0.5

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

**X intercept:**x

_{0}= 4

**Y intercept:**y

_{0}= q = 2

**Distance line from the origin:**d

_{0}= 1.7889

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

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

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

**Midpoint of the segment AB: M =**[1; 1.5]

**Perpendicular Bisector equation:**2x-y-0.5 = 0

**Vector OA = (0; 2) ; |OA| = 2**

**Vector OB = (2; 1) ; |OB| = 2.2361**

**Scalar product OA .OB = 2**

**Angle ∠ AOB = 63°26'6″ = 1.1071 rad**
