Line slope calculator 3x-4y=8


Enter coordinates of two different points:

Straight line given by points A[4; 1] and B[8; 4]

Calculation:

Slope-intercept form of line: y = 0.75x-2

Canonical form of the line equation: 3x-4y-8 = 0

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

Slope: m = 0.75

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

X intercept: x0 = 2.6667

Y intercept: y0 = q = -2

Distance line from the origin: d0 = 1.6
