Line slope calculator x+7y=29


Enter coordinates of two different points:

Straight line given by points A[1; 4] and B[8; 3]

Calculation:

Slope-intercept form of line: y = -0.1429x+4.1429

Canonical form of the line equation: x+7y-29 = 0

Parametric form of the line equation:
x = 7t+1
y = -t+4      ; t ∈ R

Slope: m = -0.1429

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

X intercept: x0 = 29

Y intercept: y0 = q = 4.1429

Distance line from the origin: d0 = 4.1012
