Line slope calculator 3x+y=12


Enter coordinates of two different points:

Straight line given by points A[2; 6] and B[3; 3]

Calculation:

Slope-intercept form of line: y = -3x+12

Canonical form of the line equation: 3x+y-12 = 0

Parametric form of the line equation:
x = t+2
y = -3t+6      ; t ∈ R

Slope: m = -3

Slope angle of line: φ = -71°33'54″ = -1.249 rad

X intercept: x0 = 4

Y intercept: y0 = q = 12

Distance line from the origin: d0 = 3.7947
