# Line slope calculator 7x+y=66

**Straight line given by points A[8; 10] and B[9; 3]**

## Calculation:

**Slope-intercept form of line:**y = -7x+66

**Canonical form of the line equation:**7x+y-66 = 0

**Parametric form of the line equation:**

x = t+8

y = -7t+10 ; t ∈ R

**Slope:**m = -7

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

**X intercept:**x

_{0}= 9.4286

**Y intercept:**y

_{0}= q = 66

**Distance line from the origin:**d

_{0}= 9.3338

**The length of the segment AB: |AB| =**7.0711

**Vector: AB =**(1; -7)

**Normal vector: n =**(7; 1)

**Midpoint of the segment AB: M =**[8.5; 6.5]
