# Line slope calculator x-7y=-5

**Straight line given by points A[2; 1] and B[9; 2]**

## Calculation:

**Slope-intercept form of line:**y = 0.1429x+0.7143

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

**Parametric form of the line equation:**

x = 7t+2

y = t+1 ; t ∈ R

**Slope:**m = 0.1429

**Slope angle of line: φ =**8°7'48″ = 0.1419 rad

**X intercept:**x

_{0}= -5

**Y intercept:**y

_{0}= q = 0.7143

**Distance line from the origin:**d

_{0}= 0.7071

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

**Vector: AB =**(7; 1)

**Normal vector: n =**(1; -7)

**Midpoint of the segment AB: M =**[5.5; 1.5]

**Perpendicular Bisector equation:**7x+y-40 = 0

**Vector OA = (2; 1) ; |OA| = 2.2361**

**Vector OB = (9; 2) ; |OB| = 9.2195**

**Scalar product OA .OB = 20**

**Angle ∠ AOB = 14°2'10″ = 0.245 rad**
