Line slope calculator x+9y=55


Enter coordinates of two different points:

Straight line given by points A[1; 6] and B[10; 5]

Calculation:

Slope-intercept form of line: y = -0.1111x+6.1111

Canonical form of the line equation: x+9y-55 = 0

Parametric form of the line equation:
x = 9t+1
y = -t+6      ; t ∈ R

Slope: m = -0.1111

Slope angle of line: φ = -6°20'25″ = -0.1107 rad

X intercept: x0 = 55

Y intercept: y0 = q = 6.1111

Distance line from the origin: d0 = 6.0737
