An equation in the form Ax+By=C |
2011-07-28 |
|
From Mike:
I need to write an equation in the form Ax+By=C
The points I was given are (5,0) and (-3,5)
I know how to find the slope I got -5/8 and wrote it out as y=(-5/8)x+b however I'm not quite sure where to go from here.
Any help would be greatly appreciated.
