# Line slope calculator 4x-7y=-10

**Straight line given by points A[1; 2] and B[8; 6]**

## Calculation:

**Slope-intercept form of line:**y = 0.5714x+1.4286

**Canonical form of the line equation:**4x-7y+10 = 0

**Parametric form of the line equation:**

x = 7t+1

y = 4t+2 ; t ∈ R

**Slope:**m = 0.5714

**Slope angle of line: φ =**29°44'42″ = 0.5191 rad

**X intercept:**x

_{0}= -2.5

**Y intercept:**y

_{0}= q = 1.4286

**Distance line from the origin:**d

_{0}= 1.2403

**The length of the segment AB: |AB| =**8.0623

**Vector: AB =**(7; 4)

**Normal vector: n =**(4; -7)

**Midpoint of the segment AB: M =**[4.5; 4]

**Perpendicular Bisector equation:**7x+4y-47.5 = 0

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

**Vector OB = (8; 6) ; |OB| = 10**

**Scalar product OA .OB = 20**
