Line slope calculator 3x-4y=9


Enter coordinates of two different points:

Straight line given by points A[3; 0] and B[7; 3]

Calculation:

Slope-intercept form of line: y = 0.75x-2.25

Canonical form of the line equation: 3x-4y-9 = 0

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

Slope: m = 0.75

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

X intercept: x0 = 3

Y intercept: y0 = q = -2.25

Distance line from the origin: d0 = 1.8
