Line slope diagram

Straight line given by points A[4; 1] and B[5; 5]

Calculation:

Slope: m = 4

Slope-intercept form of line: y = 4x-15

Canonical form of the line equation: 4x-y-15 = 0

Parametric form of the line equation:
x = t+4
y = 4t+1      ; t ∈ R

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

X intercept: x0 = 3.75

Y intercept: y0 = q = -15

Distance line from the origin: d0 = 3.638

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

Vector: AB = (1; 4)

Normal vector: n = (4; -1)

Midpoint of the segment AB: M = [4.5; 3]
