Line slope calculator 7x+2y=51


Enter coordinates of two different points:

Straight line given by points A[5; 8] and B[7; 1]

Calculation:

Slope-intercept form of line: y = -3.5x+25.5

Canonical form of the line equation: 7x+2y-51 = 0

Parametric form of the line equation:
x = 2t+5
y = -7t+8      ; t ∈ R

Slope: m = -3.5

Slope angle of line: φ = -74°3'17″ = -1.2925 rad

X intercept: x0 = 7.2857

Y intercept: y0 = q = 25.5

Distance line from the origin: d0 = 7.0054

The length of the segment AB: |AB| = 7.2801

Vector: AB = (2; -7)

Normal vector: n = (7; 2)
