Line slope calculator 3x+4y=47


Enter coordinates of two different points:

Straight line given by points A[5; 8] and B[9; 5]

Calculation:

Slope-intercept form of line: y = -0.75x+11.75

Canonical form of the line equation: 3x+4y-47 = 0

Parametric form of the line equation:
x = 4t+5
y = -3t+8      ; t ∈ R

Slope: m = -0.75

Slope angle of line: φ = -36°52'12″ = -0.6435 rad

X intercept: x0 = 15.6667

Y intercept: y0 = q = 11.75

Distance line from the origin: d0 = 9.4
