Line slope calculator 4x-y=3


Enter coordinates of two different points:

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

Calculation:

Slope-intercept form of line: y = 4x-3

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

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

Slope: m = 4

Slope angle of line: φ = 75°57'50″ = 1.3258 rad

X intercept: x0 = 0.75

Y intercept: y0 = q = -3

Distance line from the origin: d0 = 0.7276
