Line slope calculator x+y=8


Enter coordinates of two different points:

Straight line given by points A[0; 8] and B[2; 6]

Calculation:

Slope-intercept form of line: y = -x+8

Canonical form of the line equation: x+y-8 = 0

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

Slope: m = -1

Slope angle of line: φ = -45° = -0.7854 rad

X intercept: x0 = 8

Y intercept: y0 = q = 8

Distance line from the origin: d0 = 5.6569

The length of the segment AB: |AB| = 2.8284

Vector: AB = (2; -2)

Normal vector: n = (1; 1)

Midpoint of the segment AB: M = [1; 7]

Perpendicular Bisector equation: 2x-2y+12 = 0


Vector OA = (0; 8) ;   |OA| = 8
Vector OB = (2; 6) ;   |OB| = 6.3246
Scalar product OA .OB = 48
Angle ∠ AOB = 18°26'6″ = 0.3218 rad
