Line slope calculator 4x-9y=4


Enter coordinates of two different points:

Straight line given by points A[1; 0] and B[10; 4]

Calculation:

Slope-intercept form of line: y = 0.4444x-0.4444

Canonical form of the line equation: 4x-9y-4 = 0

Parametric form of the line equation:
x = 9t+1
y = 4t      ; t ∈ R

Slope: m = 0.4444

Slope angle of line: φ = 23°57'45″ = 0.4182 rad

X intercept: x0 = 1

Y intercept: y0 = q = -0.4444

Distance line from the origin: d0 = 0.4061
