# Line slope calculator 3x-4y=4

**Straight line given by points A[4; 2] and B[8; 5]**

## Calculation:

**Slope-intercept form of line:**y = 0.75x-1

**Canonical form of the line equation:**3x-4y-4 = 0

**Parametric form of the line equation:**

x = 4t+4

y = 3t+2 ; t ∈ R

**Slope:**m = 0.75

**Slope angle of line: φ =**36°52'12″ = 0.6435 rad

**X intercept:**x

_{0}= 1.3333

**Y intercept:**y

_{0}= q = -1

**Distance line from the origin:**d

_{0}= 0.8

**The length of the segment AB: |AB| =**5

**Vector: AB =**(4; 3)

**Normal vector: n =**(3; -4)

**Midpoint of the segment AB: M =**[6; 3.5]

**Perpendicular Bisector equation:**4x+3y-34.5 = 0

**Vector OA = (4; 2) ; |OA| = 4.4721**

**Vector OB = (8; 5) ; |OB| = 9.434**

**Scalar product OA .OB = 42**

**Angle ∠ AOB = 5°26'25″ = 0.095 rad**
