Line slope calculator 3x-y=19


Enter coordinates of two different points:

Straight line given by points A[7; 2] and B[8; 5]

Calculation:

Slope-intercept form of line: y = 3x-19

Canonical form of the line equation: 3x-y-19 = 0

Parametric form of the line equation:
x = t+7
y = 3t+2      ; t ∈ R

Slope: m = 3

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

X intercept: x0 = 6.3333

Y intercept: y0 = q = -19

Distance line from the origin: d0 = 6.0083
