Line slope calculator 2x+9y=90


Enter coordinates of two different points:

Straight line given by points A[0; 10] and B[9; 8]

Calculation:

Slope-intercept form of line: y = -0.2222x+10

Canonical form of the line equation: 2x+9y-90 = 0

Parametric form of the line equation:
x = 9t
y = -2t+10      ; t ∈ R

Slope: m = -0.2222

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

X intercept: x0 = 45

Y intercept: y0 = q = 10

Distance line from the origin: d0 = 9.7619

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; 9]

Perpendicular Bisector equation: 9x-2y-22.5 = 0


Vector OA = (0; 10) ;   |OA| = 10
Vector OB = (9; 8) ;   |OB| = 12.0416
Scalar product OA .OB = 80
Angle ∠ AOB = 48°21'59″ = 0.8442 rad
