Line slope calculator x-8y=-15


Enter coordinates of two different points:

Straight line given by points A[1; 2] and B[9; 3]

Calculation:

Slope-intercept form of line: y = 0.125x+1.875

Canonical form of the line equation: x-8y+15 = 0

Parametric form of the line equation:
x = 8t+1
y = t+2      ; t ∈ R

Slope: m = 0.125

Slope angle of line: φ = 7°7'30″ = 0.1244 rad

X intercept: x0 = -15

Y intercept: y0 = q = 1.875

Distance line from the origin: d0 = 1.8605
