Line slope calculator x-7y=-20


Enter coordinates of two different points:

Straight line given by points A[1; 3] and B[8; 4]

Calculation:

Slope-intercept form of line: y = 0.1429x+2.8571

Canonical form of the line equation: x-7y+20 = 0

Parametric form of the line equation:
x = 7t+1
y = t+3      ; t ∈ R

Slope: m = 0.1429

Slope angle of line: φ = 8°7'48″ = 0.1419 rad

X intercept: x0 = -20

Y intercept: y0 = q = 2.8571

Distance line from the origin: d0 = 2.8284

The length of the segment AB: |AB| = 7.0711

Vector: AB = (7; 1)

Normal vector: n = (1; -7)

Midpoint of the segment AB: M = [4.5; 3.5]

Perpendicular Bisector equation: 7x+y-35 = 0


Vector OA = (1; 3) ;   |OA| = 3.1623
Vector OB = (8; 4) ;   |OB| = 8.9443
