Line slope calculator 9x-y=80


Enter coordinates of two different points:

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

Calculation:

Slope-intercept form of line: y = 9x-80

Canonical form of the line equation: 9x-y-80 = 0

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

Slope: m = 9

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

X intercept: x0 = 8.8889

Y intercept: y0 = q = -80

Distance line from the origin: d0 = 8.8345

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-59 = 0


Vector OA = (9; 1) ;   |OA| = 9.0554
Vector OB = (10; 10) ;   |OB| = 14.1421
Scalar product OA .OB = 100
Angle ∠ AOB = 38°39'35″ = 0.6747 rad
