# Line slope calculator 4x+9y=94

**Straight line given by points A[1; 10] and B[10; 6]**

## Calculation:

**Slope-intercept form of line:**y = -0.4444x+10.4444

**Canonical form of the line equation:**4x+9y-94 = 0

**Parametric form of the line equation:**

x = 9t+1

y = -4t+10 ; t ∈ R

**Slope:**m = -0.4444

**Slope angle of line: φ =**-23°57'45″ = -0.4182 rad

**X intercept:**x

_{0}= 23.5

**Y intercept:**y

_{0}= q = 10.4444

**Distance line from the origin:**d

_{0}= 9.5443

**The length of the segment AB: |AB| =**9.8489

**Vector: AB =**(9; -4)

**Normal vector: n =**(4; 9)

**Midpoint of the segment AB: M =**[5.5; 8]

**Perpendicular Bisector equation:**9x-4y-17.5 = 0

**Vector OA = (1; 10) ; |OA| = 10.0499**

**Vector OB = (10; 6) ; |OB| = 11.6619**

**Scalar product OA .OB = 70**

**Angle ∠ AOB = 53°19'32″ = 0.9307 rad**
