Line slope diagram

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

Calculation:

Slope: m = -8

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

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

Parametric form of the line equation:
x = t
y = -8t+8      ; t ∈ R

Slope angle of line: φ = -82°52'30″ = -1.4464 rad

X intercept: x0 = 1

Y intercept: y0 = q = 8

Distance line from the origin: d0 = 0.9923

The length of the segment AB: |AB| = 8.0623

Vector: AB = (1; -8)

Normal vector: n = (8; 1)

Midpoint of the segment AB: M = [0.5; 4]

Perpendicular Bisector equation: x-8y+31.5 = 0

Vector OA = (0; 8) ;   |OA| = 8
Vector OB = (1; 0) ;   |OB| = 1
Scalar product OA .OB = 0
