# Line slope calculator -y=-4

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

## Calculation:

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

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

**Parametric form of the line equation:**

x = t

y = 4 ; t ∈ R

**Slope:**m = 0

**Slope angle of line: φ =**0° = 0 rad

**X intercept:**x

_{0}= N/A

**Y intercept:**y

_{0}= q = 4

**Distance line from the origin:**d

_{0}= 4

**The length of the segment AB: |AB| =**1

**Vector: AB =**(1; 0)

**Normal vector: n =**(0; -1)

**Midpoint of the segment AB: M =**[0.5; 4]

**Perpendicular Bisector equation:**x-0.5 = 0

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

**Vector OB = (1; 4) ; |OB| = 4.1231**

**Scalar product OA .OB = 16**

**Angle ∠ AOB = 14°2'10″ = 0.245 rad**
