# Line slope calculator 7x+y=10

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

## Calculation:

**Slope-intercept form of line:**y = -7x+10

**Canonical form of the line equation:**7x+y-10 = 0

**Parametric form of the line equation:**

x = t

y = -7t+10 ; t ∈ R

**Slope:**m = -7

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

**X intercept:**x

_{0}= 1.4286

**Y intercept:**y

_{0}= q = 10

**Distance line from the origin:**d

_{0}= 1.4142

**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+45 = 0

**Vector OA = (0; 10) ; |OA| = 10**

**Vector OB = (1; 3) ; |OB| = 3.1623**

**Scalar product OA .OB = 30**

**Angle ∠ AOB = 18°26'6″ = 0.3218 rad**
