Line slope calculator 2x+8y=82


Enter coordinates of two different points:

Straight line given by points A[1; 10] and B[9; 8]

Calculation:

Slope-intercept form of line: y = -0.25x+10.25

Canonical form of the line equation: 2x+8y-82 = 0

Parametric form of the line equation:
x = 8t+1
y = -2t+10      ; t ∈ R

Slope: m = -0.25

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

X intercept: x0 = 41

Y intercept: y0 = q = 10.25

Distance line from the origin: d0 = 9.944
