Line slope calculator 8x-y=72


Enter coordinates of two different points:

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

Calculation:

Slope-intercept form of line: y = 8x-72

Canonical form of the line equation: 8x-y-72 = 0

Parametric form of the line equation:
x = t+9
y = 8t      ; t ∈ R

Slope: m = 8

Slope angle of line: φ = 82°52'30″ = 1.4464 rad

X intercept: x0 = 9

Y intercept: y0 = q = -72

Distance line from the origin: d0 = 8.9305

The length of the segment AB: |AB| = 8.0623

Vector: AB = (1; 8)

Normal vector: n = (8; -1)

Midpoint of the segment AB: M = [9.5; 4]

Perpendicular Bisector equation: x+8y-41.5 = 0


Vector OA = (9; 0) ;   |OA| = 9
Vector OB = (10; 8) ;   |OB| = 12.8062
