Line slope calculator 3x+y=7


Enter coordinates of two different points:

Straight line given by points A[1; 4] and B[2; 1]

Calculation:

Slope-intercept form of line: y = -3x+7

Canonical form of the line equation: 3x+y-7 = 0

Parametric form of the line equation:
x = t+1
y = -3t+4      ; t ∈ R

Slope: m = -3

Slope angle of line: φ = -71°33'54″ = -1.249 rad

X intercept: x0 = 2.3333

Y intercept: y0 = q = 7

Distance line from the origin: d0 = 2.2136

The length of the segment AB: |AB| = 3.1623

Vector: AB = (1; -3)

Normal vector: n = (3; 1)

Midpoint of the segment AB: M = [1.5; 2.5]

Perpendicular Bisector equation: x-3y+6 = 0


Vector OA = (1; 4) ;   |OA| = 4.1231
Vector OB = (2; 1) ;   |OB| = 2.2361
Scalar product OA .OB = 6
Angle ∠ AOB = 49°23'55″ = 0.8622 rad
