Line slope calculator 2x-9y=-9


Enter coordinates of two different points:

Straight line given by points A[0; 1] and B[9; 3]

Calculation:

Slope-intercept form of line: y = 0.2222x+1

Canonical form of the line equation: 2x-9y+9 = 0

Parametric form of the line equation:
x = 9t
y = 2t+1      ; t ∈ R

Slope: m = 0.2222

Slope angle of line: φ = 12°31'44″ = 0.2187 rad

X intercept: x0 = -4.5

Y intercept: y0 = q = 1

Distance line from the origin: d0 = 0.9762

The length of the segment AB: |AB| = 9.2195

Vector: AB = (9; 2)

Normal vector: n = (2; -9)

Midpoint of the segment AB: M = [4.5; 2]

Perpendicular Bisector equation: 9x+2y-44.5 = 0


Vector OA = (0; 1) ;   |OA| = 1
Vector OB = (9; 3) ;   |OB| = 9.4868
