# Line slope calculator 7x+5y=61

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

## Calculation:

**Slope-intercept form of line:**y = -1.4x+12.2

**Canonical form of the line equation:**7x+5y-61 = 0

**Parametric form of the line equation:**

x = 5t+3

y = -7t+8 ; t ∈ R

**Slope:**m = -1.4

**Slope angle of line: φ =**-54°27'44″ = -0.9505 rad

**X intercept:**x

_{0}= 8.7143

**Y intercept:**y

_{0}= q = 12.2

**Distance line from the origin:**d

_{0}= 7.0911

**The length of the segment AB: |AB| =**8.6023

**Vector: AB =**(5; -7)

**Normal vector: n =**(7; 5)

**Midpoint of the segment AB: M =**[5.5; 4.5]

**Perpendicular Bisector equation:**5x-7y+4 = 0

**Vector OA = (3; 8) ; |OA| = 8.544**

**Vector OB = (8; 1) ; |OB| = 8.0623**

**Scalar product OA .OB = 32**

**Angle ∠ AOB = 62°19'8″ = 1.0877 rad**
