Line slope calculator 2x+7y=28


Enter coordinates of two different points:

Straight line given by points A[0; 4] and B[7; 2]

Calculation:

Slope-intercept form of line: y = -0.2857x+4

Canonical form of the line equation: 2x+7y-28 = 0

Parametric form of the line equation:
x = 7t
y = -2t+4      ; t ∈ R

Slope: m = -0.2857

Slope angle of line: φ = -15°56'43″ = -0.2783 rad

X intercept: x0 = 14

Y intercept: y0 = q = 4

Distance line from the origin: d0 = 3.8461

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

Vector: AB = (7; -2)
