# Line slope calculator x-2y=-8

**Straight line given by points A[0; 4] and B[2; 5]**

## Calculation:

**Slope-intercept form of line:**y = 0.5x+4

**Canonical form of the line equation:**x-2y+8 = 0

**Parametric form of the line equation:**

x = 2t

y = t+4 ; t ∈ R

**Slope:**m = 0.5

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

**X intercept:**x

_{0}= -8

**Y intercept:**y

_{0}= q = 4

**Distance line from the origin:**d

_{0}= 3.5777

**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; 4.5]

**Perpendicular Bisector equation:**2x+y-6.5 = 0

**Vector OA = (0; 4) ; |OA| = 4**

**Vector OB = (2; 5) ; |OB| = 5.3852**

**Scalar product OA .OB = 20**

**Angle ∠ AOB = 21°48'5″ = 0.3805 rad**
