Line slope diagram

Straight line given by points A[0; 4] and B[1; 8]

Calculation:

Slope: m = 4

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

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

Parametric form of the line equation:
x = t
y = 4t+4      ; t ∈ R

Slope angle of line: φ = 75°57'50″ = 1.3258 rad

X intercept: x0 = -1

Y intercept: y0 = q = 4

Distance line from the origin: d0 = 0.9701

The length of the segment AB: |AB| = 4.1231

Vector: AB = (1; 4)

Normal vector: n = (4; -1)

Midpoint of the segment AB: M = [0.5; 6]

Perpendicular Bisector equation: x+4y-24.5 = 0

Vector OA = (0; 4) ;   |OA| = 4
