Line slope calculator 5x+y=21


Enter coordinates of two different points:

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

Calculation:

Slope-intercept form of line: y = -5x+21

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

Parametric form of the line equation:
x = t+3
y = -5t+6      ; t ∈ R

Slope: m = -5

Slope angle of line: φ = -78°41'24″ = -1.3734 rad

X intercept: x0 = 4.2

Y intercept: y0 = q = 21

Distance line from the origin: d0 = 4.1184
