Line slope diagram

Straight line given by points A[0; 1] and B[1; 10]

Calculation:

Slope: m = 9

Slope-intercept form of line: y = 9x+1

Canonical form of the line equation: 9x-y+1 = 0

Parametric form of the line equation:
x = t
y = 9t+1      ; t ∈ R

Slope angle of line: φ = 83°39'35″ = 1.4601 rad

X intercept: x0 = -0.1111

Y intercept: y0 = q = 1

Distance line from the origin: d0 = 0.1104

The length of the segment AB: |AB| = 9.0554

Vector: AB = (1; 9)

Normal vector: n = (9; -1)

Midpoint of the segment AB: M = [0.5; 5.5]

Perpendicular Bisector equation: x+9y-50 = 0

Vector OA = (0; 1) ;   |OA| = 1
Vector OB = (1; 10) ;   |OB| = 10.0499
Scalar product OA .OB = 10
Angle ∠ AOB = 5°42'38″ = 0.0997 rad
