Line slope calculator x+4y=23


Enter coordinates of two different points:

Straight line given by points A[3; 5] and B[7; 4]

Calculation:

Slope-intercept form of line: y = -0.25x+5.75

Canonical form of the line equation: x+4y-23 = 0

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

Slope: m = -0.25

Slope angle of line: φ = -14°2'10″ = -0.245 rad

X intercept: x0 = 23

Y intercept: y0 = q = 5.75

Distance line from the origin: d0 = 5.5783
