Line slope diagram

Straight line given by points A[0; 1] and B[2; 10]

Calculation:

Slope: m = 4.5

Slope-intercept form of line: y = 4.5x+1

Canonical form of the line equation: 9x-2y+2 = 0

Parametric form of the line equation:
x = 2t
y = 9t+1      ; t ∈ R

Slope angle of line: φ = 77°28'16″ = 1.3521 rad

X intercept: x0 = -0.2222

Y intercept: y0 = q = 1

Distance line from the origin: d0 = 0.2169
