Line slope diagram

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

Calculation:

Slope: m = 1

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 angle of line: φ = 45° = 0.7854 rad

X intercept: x0 = 8

Y intercept: y0 = q = -8

Distance line from the origin: d0 = 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
