Line slope calculator x-2y=-1


Enter coordinates of two different points:

Straight line given by points A[1; 1] and B[3; 2]

Calculation:

Slope-intercept form of line: y = 0.5x+0.5

Canonical form of the line equation: x-2y+1 = 0

Parametric form of the line equation:
x = 2t+1
y = t+1      ; t ∈ R

Slope: m = 0.5

Slope angle of line: φ = 26°33'54″ = 0.4636 rad

X intercept: x0 = -1

Y intercept: y0 = q = 0.5

Distance line from the origin: d0 = 0.4472
