# Line slope calculator x-7y=-28

**Straight line given by points A[0; 4] and B[7; 5]**

## Calculation:

**Slope-intercept form of line:**y = 0.1429x+4

**Canonical form of the line equation:**x-7y+28 = 0

**Parametric form of the line equation:**

x = 7t

y = t+4 ; t ∈ R

**Slope:**m = 0.1429

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

**X intercept:**x

_{0}= -28

**Y intercept:**y

_{0}= q = 4

**Distance line from the origin:**d

_{0}= 3.9598

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

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

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

**Midpoint of the segment AB: M =**[3.5; 4.5]

**Perpendicular Bisector equation:**7x+y-29 = 0

**Vector OA = (0; 4) ; |OA| = 4**

**Vector OB = (7; 5) ; |OB| = 8.6023**

**Scalar product OA .OB = 20**

**Angle ∠ AOB = 54°27'44″ = 0.9505 rad**
