Line slope calculator x+5y=21


Enter coordinates of two different points:

Straight line given by points A[1; 4] and B[6; 3]

Calculation:

Slope-intercept form of line: y = -0.2x+4.2

Canonical form of the line equation: x+5y-21 = 0

Parametric form of the line equation:
x = 5t+1
y = -t+4      ; t ∈ R

Slope: m = -0.2

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

X intercept: x0 = 21

Y intercept: y0 = q = 4.2

Distance line from the origin: d0 = 4.1184
