Line slope calculator 2x+8y=66


Enter coordinates of two different points:

Straight line given by points A[1; 8] and B[9; 6]

Calculation:

Slope-intercept form of line: y = -0.25x+8.25

Canonical form of the line equation: 2x+8y-66 = 0

Parametric form of the line equation:
x = 8t+1
y = -2t+8      ; t ∈ R

Slope: m = -0.25

Slope angle of line: φ = -14°2'10″ = -0.245 rad

X intercept: x0 = 33

Y intercept: y0 = q = 8.25

Distance line from the origin: d0 = 8.0037
