# Line slope calculator x+y=7

**Straight line given by points A[1; 6] and B[2; 5]**

## 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+6 ; 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| =**1.4142

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

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

**Midpoint of the segment AB: M =**[1.5; 5.5]

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

**Vector OA = (1; 6) ; |OA| = 6.0828**

**Vector OB = (2; 5) ; |OB| = 5.3852**

**Scalar product OA .OB = 32**

**Angle ∠ AOB = 12°20'21″ = 0.2154 rad**
