Line slope calculator 7x-4y=3


Enter coordinates of two different points:

Straight line given by points A[1; 1] and B[5; 8]

Calculation:

Slope-intercept form of line: y = 1.75x-0.75

Canonical form of the line equation: 7x-4y-3 = 0

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

Slope: m = 1.75

Slope angle of line: φ = 60°15'18″ = 1.0517 rad

X intercept: x0 = 0.4286

Y intercept: y0 = q = -0.75

Distance line from the origin: d0 = 0.3721
