Line slope calculator 2x-9y=-18


Enter coordinates of two different points:

Straight line given by points A[0; 2] and B[9; 4]

Calculation:

Slope-intercept form of line: y = 0.2222x+2

Canonical form of the line equation: 2x-9y+18 = 0

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

Slope: m = 0.2222

Slope angle of line: φ = 12°31'44″ = 0.2187 rad

X intercept: x0 = -9

Y intercept: y0 = q = 2

Distance line from the origin: d0 = 1.9524

The length of the segment AB: |AB| = 9.2195

Vector: AB = (9; 2)

Normal vector: n = (2; -9)

Midpoint of the segment AB: M = [4.5; 3]
