Line slope calculator x+8y=49


Enter coordinates of two different points:

Straight line given by points A[1; 6] and B[9; 5]

Calculation:

Slope-intercept form of line: y = -0.125x+6.125

Canonical form of the line equation: x+8y-49 = 0

Parametric form of the line equation:
x = 8t+1
y = -t+6      ; t ∈ R

Slope: m = -0.125

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

X intercept: x0 = 49

Y intercept: y0 = q = 6.125

Distance line from the origin: d0 = 6.0777
