Line slope calculator x+2y=9


Enter coordinates of two different points:

Straight line given by points A[1; 4] and B[3; 3]

Calculation:

Slope-intercept form of line: y = -0.5x+4.5

Canonical form of the line equation: x+2y-9 = 0

Parametric form of the line equation:
x = 2t+1
y = -t+4      ; t ∈ R

Slope: m = -0.5

Slope angle of line: φ = -26°33'54″ = -0.4636 rad

X intercept: x0 = 9

Y intercept: y0 = q = 4.5

Distance line from the origin: d0 = 4.0249
