# Line slope calculator 7x-y=-3

**Straight line given by points A[0; 3] and B[1; 10]**

## Calculation:

**Slope-intercept form of line:**y = 7x+3

**Canonical form of the line equation:**7x-y+3 = 0

**Parametric form of the line equation:**

x = t

y = 7t+3 ; t ∈ R

**Slope:**m = 7

**Slope angle of line: φ =**81°52'12″ = 1.4289 rad

**X intercept:**x

_{0}= -0.4286

**Y intercept:**y

_{0}= q = 3

**Distance line from the origin:**d

_{0}= 0.4243

**The length of the segment AB: |AB| =**7.0711

**Vector: AB =**(1; 7)

**Normal vector: n =**(7; -1)

**Midpoint of the segment AB: M =**[0.5; 6.5]

**Perpendicular Bisector equation:**x+7y-46 = 0

**Vector OA = (0; 3) ; |OA| = 3**

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

**Scalar product OA .OB = 30**

**Angle ∠ AOB = 5°42'38″ = 0.0997 rad**
