# Line slope calculator x-y=-7

**Straight line given by points A[1; 8] and B[3; 10]**

## Calculation:

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

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

**Parametric form of the line equation:**

x = t+1

y = t+8 ; t ∈ R

**Slope:**m = 1

**Slope angle of line: φ =**45° = 0.7854 rad

**X intercept:**x

_{0}= -7

**Y intercept:**y

_{0}= q = 7

**Distance line from the origin:**d

_{0}= 4.9497

**The length of the segment AB: |AB| =**2.8284

**Vector: AB =**(2; 2)

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

**Midpoint of the segment AB: M =**[2; 9]

**Perpendicular Bisector equation:**2x+2y-22 = 0

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

**Vector OB = (3; 10) ; |OB| = 10.4403**

**Scalar product OA .OB = 83**

**Angle ∠ AOB = 9°34'27″ = 0.1671 rad**
