Line slope calculator 2x-y=15


Enter coordinates of two different points:

Straight line given by points A[8; 1] and B[9; 3]

Calculation:

Slope-intercept form of line: y = 2x-15

Canonical form of the line equation: 2x-y-15 = 0

Parametric form of the line equation:
x = t+8
y = 2t+1      ; t ∈ R

Slope: m = 2

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

X intercept: x0 = 7.5

Y intercept: y0 = q = -15

Distance line from the origin: d0 = 6.7082
