Line slope calculator 7x-y=20


Enter coordinates of two different points:

Straight line given by points A[3; 1] and B[4; 8]

Calculation:

Slope-intercept form of line: y = 7x-20

Canonical form of the line equation: 7x-y-20 = 0

Parametric form of the line equation:
x = t+3
y = 7t+1      ; t ∈ R

Slope: m = 7

Slope angle of line: φ = 81°52'12″ = 1.4289 rad

X intercept: x0 = 2.8571

Y intercept: y0 = q = -20

Distance line from the origin: d0 = 2.8284

The length of the segment AB: |AB| = 7.0711

Vector: AB = (1; 7)

Normal vector: n = (7; -1)

Midpoint of the segment AB: M = [3.5; 4.5]

Perpendicular Bisector equation: x+7y-35 = 0


Vector OA = (3; 1) ;   |OA| = 3.1623
Vector OB = (4; 8) ;   |OB| = 8.9443
Scalar product OA .OB = 20
