# Line slope calculator 9x-y=8

**Straight line given by points A[1; 1] and B[2; 10]**

## Calculation:

**Slope-intercept form of line:**y = 9x-8

**Canonical form of the line equation:**9x-y-8 = 0

**Parametric form of the line equation:**

x = t+1

y = 9t+1 ; t ∈ R

**Slope:**m = 9

**Slope angle of line: φ =**83°39'35″ = 1.4601 rad

**X intercept:**x

_{0}= 0.8889

**Y intercept:**y

_{0}= q = -8

**Distance line from the origin:**d

_{0}= 0.8835

**The length of the segment AB: |AB| =**9.0554

**Vector: AB =**(1; 9)

**Normal vector: n =**(9; -1)

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

**Perpendicular Bisector equation:**x+9y-51 = 0

**Vector OA = (1; 1) ; |OA| = 1.4142**

**Vector OB = (2; 10) ; |OB| = 10.198**

**Scalar product OA .OB = 12**

**Angle ∠ AOB = 33°41'24″ = 0.588 rad**
