Line slope calculator 3x-4y=-9


Enter coordinates of two different points:

Straight line given by points A[1; 3] and B[5; 6]

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+1
y = 3t+3      ; 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
