Line slope calculator 4x-y=28


Enter coordinates of two different points:

Straight line given by points A[7; 0] and B[8; 4]

Calculation:

Slope-intercept form of line: y = 4x-28

Canonical form of the line equation: 4x-y-28 = 0

Parametric form of the line equation:
x = t+7
y = 4t      ; t ∈ R

Slope: m = 4

Slope angle of line: φ = 75°57'50″ = 1.3258 rad

X intercept: x0 = 7

Y intercept: y0 = q = -28

Distance line from the origin: d0 = 6.791
