# Line slope calculator 2x-y=15

**Straight line given by points A[8; 1] and B[9; 3]**

## Calculation:

**Slope-intercept form of line:**y = 2x-15

**Canonical form of the line equation:**2x-y-15 = 0

**Parametric form of the line equation:**

x = t+8

y = 2t+1 ; t ∈ R

**Slope:**m = 2

**Slope angle of line: φ =**63°26'6″ = 1.1071 rad

**X intercept:**x

_{0}= 7.5

**Y intercept:**y

_{0}= q = -15

**Distance line from the origin:**d

_{0}= 6.7082

**The length of the segment AB: |AB| =**2.2361

**Vector: AB =**(1; 2)

**Normal vector: n =**(2; -1)

**Midpoint of the segment AB: M =**[8.5; 2]

**Perpendicular Bisector equation:**x+2y-12.5 = 0

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

**Vector OB = (9; 3) ; |OB| = 9.4868**

**Scalar product OA .OB = 75**

**Angle ∠ AOB = 11°18'36″ = 0.1974 rad**
