y-%28-3%29=%28%28-8-%28-3%29%29%2F%284-7%29%29%28x-7%29-------------this is starting as point-slope form.
-
y%2B3=%285%2F3%29%28x-7%29
3y%2B9=5%28x-7%29
3y%2B9=5x-35
3y-5x=-35-9
3y-5x=-44-----------from this, multiply left and right by -1.
5x-3y=44--------------standard form

Write the standard form of the line that passes through the given points. Include your work in your final answer.
(7, -3) and (4, -8)
====================

|x   y   1|
|7  -3   1| = 0
|4  -8   1|

x*(-3*1 - (-8)*1) - y*(7*1 - 4*1) + 1*(7*-8 - 4*-3) = 0
5x - 3y - 44 = 0
