Line slope calculator 8x-9y=-18


Enter coordinates of two different points:

Straight line given by points A[0; 2] and B[9; 10]

Calculation:

Slope-intercept form of line: y = 0.8889x+2

Canonical form of the line equation: 8x-9y+18 = 0

Parametric form of the line equation:
x = 9t
y = 8t+2      ; t ∈ R

Slope: m = 0.8889

Slope angle of line: φ = 41°38'1″ = 0.7266 rad

X intercept: x0 = -2.25

Y intercept: y0 = q = 2

Distance line from the origin: d0 = 1.4948
