Line slope calculator x+4y=19


Enter coordinates of two different points:

Straight line given by points A[3; 4] and B[7; 3]

Calculation:

Slope-intercept form of line: y = -0.25x+4.75

Canonical form of the line equation: x+4y-19 = 0

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

Slope: m = -0.25

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

X intercept: x0 = 19

Y intercept: y0 = q = 4.75

Distance line from the origin: d0 = 4.6082

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; 3.5]

Perpendicular Bisector equation: 4x-y-16.5 = 0


Vector OA = (3; 4) ;   |OA| = 5
Vector OB = (7; 3) ;   |OB| = 7.6158
Scalar product OA .OB = 33
Angle ∠ AOB = 29°55'53″ = 0.5224 rad
