Line slope calculator 7x+4y=60


Enter coordinates of two different points:

Straight line given by points A[4; 8] and B[8; 1]

Calculation:

Slope-intercept form of line: y = -1.75x+15

Canonical form of the line equation: 7x+4y-60 = 0

Parametric form of the line equation:
x = 4t+4
y = -7t+8      ; t ∈ R

Slope: m = -1.75

Slope angle of line: φ = -60°15'18″ = -1.0517 rad

X intercept: x0 = 8.5714

Y intercept: y0 = q = 15

Distance line from the origin: d0 = 7.4421

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

Vector: AB = (4; -7)

Normal vector: n = (7; 4)

Midpoint of the segment AB: M = [6; 4.5]

Perpendicular Bisector equation: 4x-7y+7.5 = 0


Vector OA = (4; 8) ;   |OA| = 8.9443
Vector OB = (8; 1) ;   |OB| = 8.0623
