Line slope calculator 3x+8y=64


Enter coordinates of two different points:

Straight line given by points A[0; 8] and B[8; 5]

Calculation:

Slope-intercept form of line: y = -0.375x+8

Canonical form of the line equation: 3x+8y-64 = 0

Parametric form of the line equation:
x = 8t
y = -3t+8      ; t ∈ R

Slope: m = -0.375

Slope angle of line: φ = -20°33'22″ = -0.3588 rad

X intercept: x0 = 21.3333

Y intercept: y0 = q = 8

Distance line from the origin: d0 = 7.4906
