# Line slope calculator 4x-9y=4

**Straight line given by points A[1; 0] and B[10; 4]**

## Calculation:

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

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

**Parametric form of the line equation:**

x = 9t+1

y = 4t ; t ∈ R

**Slope:**m = 0.4444

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

**X intercept:**x

_{0}= 1

**Y intercept:**y

_{0}= q = -0.4444

**Distance line from the origin:**d

_{0}= 0.4061

**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; 2]

**Perpendicular Bisector equation:**9x+4y-57.5 = 0

**Vector OA = (1; 0) ; |OA| = 1**

**Vector OB = (10; 4) ; |OB| = 10.7703**

**Scalar product OA .OB = 10**

**Angle ∠ AOB = 21°48'5″ = 0.3805 rad**
