Line slope calculator 4x-3y=-8


Enter coordinates of two different points:

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

Calculation:

Slope-intercept form of line: y = 1.3333x+2.6667

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

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

Slope: m = 1.3333

Slope angle of line: φ = 53°7'48″ = 0.9273 rad

X intercept: x0 = -2

Y intercept: y0 = q = 2.6667

Distance line from the origin: d0 = 1.6
