Line slope calculator x+7y=9


Enter coordinates of two different points:

Straight line given by points A[2; 1] and B[9; 0]

Calculation:

Slope-intercept form of line: y = -0.1429x+1.2857

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

Parametric form of the line equation:
x = 7t+2
y = -t+1      ; t ∈ R

Slope: m = -0.1429

Slope angle of line: φ = -8°7'48″ = -0.1419 rad

X intercept: x0 = 9

Y intercept: y0 = q = 1.2857

Distance line from the origin: d0 = 1.2728
