Line slope calculator 9x+2y=20


Enter coordinates of two different points:

Straight line given by points A[0; 10] and B[2; 1]

Calculation:

Slope-intercept form of line: y = -4.5x+10

Canonical form of the line equation: 9x+2y-20 = 0

Parametric form of the line equation:
x = 2t
y = -9t+10      ; t ∈ R

Slope: m = -4.5

Slope angle of line: φ = -77°28'16″ = -1.3521 rad

X intercept: x0 = 2.2222

Y intercept: y0 = q = 10

Distance line from the origin: d0 = 2.1693
