Line slope calculator 2x+y=9


Enter coordinates of two different points:

Straight line given by points A[2; 5] and B[3; 3]

Calculation:

Slope-intercept form of line: y = -2x+9

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

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

Slope: m = -2

Slope angle of line: φ = -63°26'6″ = -1.1071 rad

X intercept: x0 = 4.5

Y intercept: y0 = q = 9

Distance line from the origin: d0 = 4.0249
