Line slope calculator 3x+4y=19


Enter coordinates of two different points:

Straight line given by points A[1; 4] and B[5; 1]

Calculation:

Slope-intercept form of line: y = -0.75x+4.75

Canonical form of the line equation: 3x+4y-19 = 0

Parametric form of the line equation:
x = 4t+1
y = -3t+4      ; t ∈ R

Slope: m = -0.75

Slope angle of line: φ = -36°52'12″ = -0.6435 rad

X intercept: x0 = 6.3333

Y intercept: y0 = q = 4.75

Distance line from the origin: d0 = 3.8
