Line slope diagram

Straight line given by points A[0; 1] and B[1; 8]

Calculation:

Slope: m = 7

Slope-intercept form of line: y = 7x+1

Canonical form of the line equation: 7x-y+1 = 0

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

Slope angle of line: φ = 81°52'12″ = 1.4289 rad

X intercept: x0 = -0.1429

Y intercept: y0 = q = 1

Distance line from the origin: d0 = 0.1414

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

Vector: AB = (1; 7)

Normal vector: n = (7; -1)

Midpoint of the segment AB: M = [0.5; 4.5]

Perpendicular Bisector equation: x+7y-32 = 0

Vector OA = (0; 1) ;   |OA| = 1
Vector OB = (1; 8) ;   |OB| = 8.0623
Scalar product OA .OB = 8
Angle ∠ AOB = 7°7'30″ = 0.1244 rad
