Line slope diagram

Straight line given by points A[9; 10] and B[10; 1]

Calculation:

Slope: m = -9

Slope-intercept form of line: y = -9x+91

Canonical form of the line equation: 9x+y-91 = 0

Parametric form of the line equation:
x = t+9
y = -9t+10      ; t ∈ R

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

X intercept: x0 = 10.1111

Y intercept: y0 = q = 91

Distance line from the origin: d0 = 10.0493

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

Vector: AB = (1; -9)

Normal vector: n = (9; 1)

Midpoint of the segment AB: M = [9.5; 5.5]

Perpendicular Bisector equation: x-9y+40 = 0

Vector OA = (9; 10) ;   |OA| = 13.4536
Vector OB = (10; 1) ;   |OB| = 10.0499
Scalar product OA .OB = 100
Angle ∠ AOB = 42°18'8″ = 0.7383 rad
