Line slope calculator 3x-7y=9


Enter coordinates of two different points:

Straight line given by points A[3; 0] and B[10; 3]

Calculation:

Slope-intercept form of line: y = 0.4286x-1.2857

Canonical form of the line equation: 3x-7y-9 = 0

Parametric form of the line equation:
x = 7t+3
y = 3t      ; t ∈ R

Slope: m = 0.4286

Slope angle of line: φ = 23°11'55″ = 0.4049 rad

X intercept: x0 = 3

Y intercept: y0 = q = -1.2857

Distance line from the origin: d0 = 1.1818
