Line slope calculator 9x-7y=2


Enter coordinates of two different points:

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

Calculation:

Slope-intercept form of line: y = 1.2857x-0.2857

Canonical form of the line equation: 9x-7y-2 = 0

Parametric form of the line equation:
x = 7t+1
y = 9t+1      ; t ∈ R

Slope: m = 1.2857

Slope angle of line: φ = 52°7'30″ = 0.9098 rad

X intercept: x0 = 0.2222

Y intercept: y0 = q = -0.2857

Distance line from the origin: d0 = 0.1754
