Line slope calculator x-8y=-7


Enter coordinates of two different points:

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

Calculation:

Slope-intercept form of line: y = 0.125x+0.875

Canonical form of the line equation: x-8y+7 = 0

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

Slope: m = 0.125

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

X intercept: x0 = -7

Y intercept: y0 = q = 0.875

Distance line from the origin: d0 = 0.8682
