Line slope calculator x+5y=18


Enter coordinates of two different points:

Straight line given by points A[3; 3] and B[8; 2]

Calculation:

Slope-intercept form of line: y = -0.2x+3.6

Canonical form of the line equation: x+5y-18 = 0

Parametric form of the line equation:
x = 5t+3
y = -t+3      ; t ∈ R

Slope: m = -0.2

Slope angle of line: φ = -11°18'36″ = -0.1974 rad

X intercept: x0 = 18

Y intercept: y0 = q = 3.6

Distance line from the origin: d0 = 3.5301
