A line on a coordinate grid passes through (-3,6) and (5,-6). What is the equation of the line?
~~~~~~~~~~~~~~~~~
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."
