# Line slope calculator 4x-y=-4

**Straight line given by points A[0; 4] and B[1; 8]**

## Calculation:

**Slope-intercept form of line:**y = 4x+4

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

**Parametric form of the line equation:**

x = t

y = 4t+4 ; t ∈ R

**Slope:**m = 4

**Slope angle of line: φ =**75°57'50″ = 1.3258 rad

**X intercept:**x

_{0}= -1

**Y intercept:**y

_{0}= q = 4

**Distance line from the origin:**d

_{0}= 0.9701

**The length of the segment AB: |AB| =**4.1231

**Vector: AB =**(1; 4)

**Normal vector: n =**(4; -1)

**Midpoint of the segment AB: M =**[0.5; 6]

**Perpendicular Bisector equation:**x+4y-24.5 = 0

**Vector OA = (0; 4) ; |OA| = 4**

**Vector OB = (1; 8) ; |OB| = 8.0623**

**Scalar product OA .OB = 32**

**Angle ∠ AOB = 7°7'30″ = 0.1244 rad**
