Line slope calculator 10x+9y=100


Enter coordinates of two different points:

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

Calculation:

Slope-intercept form of line: y = -1.1111x+11.1111

Canonical form of the line equation: 10x+9y-100 = 0

Parametric form of the line equation:
x = 9t+1
y = -10t+10      ; t ∈ R

Slope: m = -1.1111

Slope angle of line: φ = -48°46″ = -0.838 rad

X intercept: x0 = 10

Y intercept: y0 = q = 11.1111

Distance line from the origin: d0 = 7.4329
