Line slope calculator 4x-9y=-54


Enter coordinates of two different points:

Straight line given by points A[0; 6] and B[9; 10]

Calculation:

Slope-intercept form of line: y = 0.4444x+6

Canonical form of the line equation: 4x-9y+54 = 0

Parametric form of the line equation:
x = 9t
y = 4t+6      ; t ∈ R

Slope: m = 0.4444

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

X intercept: x0 = -13.5

Y intercept: y0 = q = 6

Distance line from the origin: d0 = 5.4829
