Line slope calculator 4x-7y=1


Enter coordinates of two different points:

Straight line given by points A[2; 1] and B[9; 5]

Calculation:

Slope-intercept form of line: y = 0.5714x-0.1429

Canonical form of the line equation: 4x-7y-1 = 0

Parametric form of the line equation:
x = 7t+2
y = 4t+1      ; t ∈ R

Slope: m = 0.5714

Slope angle of line: φ = 29°44'42″ = 0.5191 rad

X intercept: x0 = 0.25

Y intercept: y0 = q = -0.1429

Distance line from the origin: d0 = 0.124
