Line slope calculator x+4y=7


Enter coordinates of two different points:

Straight line given by points A[3; 1] and B[7; 0]

Calculation:

Slope-intercept form of line: y = -0.25x+1.75

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

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

Slope: m = -0.25

Slope angle of line: φ = -14°2'10″ = -0.245 rad

X intercept: x0 = 7

Y intercept: y0 = q = 1.75

Distance line from the origin: d0 = 1.6977

The length of the segment AB: |AB| = 4.1231

Vector: AB = (4; -1)

Normal vector: n = (1; 4)

Midpoint of the segment AB: M = [5; 0.5]

Perpendicular Bisector equation: 4x-y-19.5 = 0


Vector OA = (3; 1) ;   |OA| = 3.1623
Vector OB = (7; 0) ;   |OB| = 7
Scalar product OA .OB = 21
Angle ∠ AOB = 18°26'6″ = 0.3218 rad
