Line slope calculator 4x+3y=28


Enter coordinates of two different points:

Straight line given by points A[1; 8] and B[4; 4]

Calculation:

Slope-intercept form of line: y = -1.3333x+9.3333

Canonical form of the line equation: 4x+3y-28 = 0

Parametric form of the line equation:
x = 3t+1
y = -4t+8      ; t ∈ R

Slope: m = -1.3333

Slope angle of line: φ = -53°7'48″ = -0.9273 rad

X intercept: x0 = 7

Y intercept: y0 = q = 9.3333

Distance line from the origin: d0 = 5.6
