# Line slope calculator x-7y=-18

**Straight line given by points A[3; 3] and B[10; 4]**

## Calculation:

**Slope-intercept form of line:**y = 0.1429x+2.5714

**Canonical form of the line equation:**x-7y+18 = 0

**Parametric form of the line equation:**

x = 7t+3

y = t+3 ; t ∈ R

**Slope:**m = 0.1429

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

**X intercept:**x

_{0}= -18

**Y intercept:**y

_{0}= q = 2.5714

**Distance line from the origin:**d

_{0}= 2.5456

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

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

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

**Midpoint of the segment AB: M =**[6.5; 3.5]

**Perpendicular Bisector equation:**7x+y-49 = 0

**Vector OA = (3; 3) ; |OA| = 4.2426**

**Vector OB = (10; 4) ; |OB| = 10.7703**

**Scalar product OA .OB = 42**

**Angle ∠ AOB = 23°11'55″ = 0.4049 rad**
