# Line slope calculator 5x-4y=-7

**Straight line given by points A[1; 3] and B[5; 8]**

## Calculation:

**Slope-intercept form of line:**y = 1.25x+1.75

**Canonical form of the line equation:**5x-4y+7 = 0

**Parametric form of the line equation:**

x = 4t+1

y = 5t+3 ; t ∈ R

**Slope:**m = 1.25

**Slope angle of line: φ =**51°20'25″ = 0.8961 rad

**X intercept:**x

_{0}= -1.4

**Y intercept:**y

_{0}= q = 1.75

**Distance line from the origin:**d

_{0}= 1.0932

**The length of the segment AB: |AB| =**6.4031

**Vector: AB =**(4; 5)

**Normal vector: n =**(5; -4)

**Midpoint of the segment AB: M =**[3; 5.5]

**Perpendicular Bisector equation:**4x+5y-39.5 = 0

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

**Vector OB = (5; 8) ; |OB| = 9.434**

**Scalar product OA .OB = 29**

**Angle ∠ AOB = 13°34'14″ = 0.2368 rad**
