Line slope calculator 2x+7y=18


Enter coordinates of two different points:

Straight line given by points A[2; 2] and B[9; 0]

Calculation:

Slope-intercept form of line: y = -0.2857x+2.5714

Canonical form of the line equation: 2x+7y-18 = 0

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

Slope: m = -0.2857

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

X intercept: x0 = 9

Y intercept: y0 = q = 2.5714

Distance line from the origin: d0 = 2.4725
