# Line slope calculator 9x-2y=7

**Straight line given by points A[1; 1] and B[3; 10]**

## Calculation:

**Slope-intercept form of line:**y = 4.5x-3.5

**Canonical form of the line equation:**9x-2y-7 = 0

**Parametric form of the line equation:**

x = 2t+1

y = 9t+1 ; t ∈ R

**Slope:**m = 4.5

**Slope angle of line: φ =**77°28'16″ = 1.3521 rad

**X intercept:**x

_{0}= 0.7778

**Y intercept:**y

_{0}= q = -3.5

**Distance line from the origin:**d

_{0}= 0.7593

**The length of the segment AB: |AB| =**9.2195

**Vector: AB =**(2; 9)

**Normal vector: n =**(9; -2)

**Midpoint of the segment AB: M =**[2; 5.5]

**Perpendicular Bisector equation:**2x+9y-53.5 = 0

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

**Vector OB = (3; 10) ; |OB| = 10.4403**

**Scalar product OA .OB = 13**

**Angle ∠ AOB = 28°18'3″ = 0.4939 rad**
