~~~~~~~~~~~~~~~~~

The slope is m =  =  =  = .


The equation of the straight line is 

y - 6 = {{(-3/2)*(x-(-3))}}},   or, which is the same,   y - 6 = ,  or, which is the same,

2y - 12 = -3x - 9,   or, which is the same,   3x + 2y = 3.

Solved.

---------

| x    y    1|
|-3    6    1| = 0
| 5   -6    1|


x*(6+6) - y*(-3-5) + 1*(18-30) = 0
12x + 8y = 12
3x + 2y = 3
==================
PS It's an equation, not "the equation."
