# Line slope calculator x-y=8

**Straight line given by points A[8; 0] and B[9; 1]**

## Calculation:

**Slope-intercept form of line:**y = x-8

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

**Parametric form of the line equation:**

x = t+8

y = t ; t ∈ R

**Slope:**m = 1

**Slope angle of line: φ =**45° = 0.7854 rad

**X intercept:**x

_{0}= 8

**Y intercept:**y

_{0}= q = -8

**Distance line from the origin:**d

_{0}= 5.6569

**The length of the segment AB: |AB| =**1.4142

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

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

**Midpoint of the segment AB: M =**[8.5; 0.5]

**Perpendicular Bisector equation:**x+y-9 = 0

**Vector OA = (8; 0) ; |OA| = 8**

**Vector OB = (9; 1) ; |OB| = 9.0554**

**Scalar product OA .OB = 72**

**Angle ∠ AOB = 6°20'25″ = 0.1107 rad**
