Line slope calculator 9x-8y=-8


Enter coordinates of two different points:

Straight line given by points A[0; 1] and B[8; 10]

Calculation:

Slope-intercept form of line: y = 1.125x+1

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

Parametric form of the line equation:
x = 8t
y = 9t+1      ; t ∈ R

Slope: m = 1.125

Slope angle of line: φ = 48°21'59″ = 0.8442 rad

X intercept: x0 = -0.8889

Y intercept: y0 = q = 1

Distance line from the origin: d0 = 0.6644
