Line slope diagram

Straight line given by points A[0; 2] and B[4; 1]

Calculation:

Slope: m = -0.25

Slope-intercept form of line: y = -0.25x+2

Canonical form of the line equation: x+4y-8 = 0

Parametric form of the line equation:
x = 4t
y = -t+2      ; t ∈ R

Slope angle of line: φ = -14°2'10″ = -0.245 rad

X intercept: x0 = 8

Y intercept: y0 = q = 2

Distance line from the origin: d0 = 1.9403
