SOLUTION: Find an equation for the line: through (-5,1) and perpendicular to y=3x-4.
m=-1/3 y=mx+b
1=-1/3(-5)+b
1=5/3+b
3/5=b
ANSWER: Y=-1/3X+3/5 Is this correct??

You can put this solution on YOUR website!
Missed it by THAT much (he said holding his thumb and forefinger apart with a scant millimeter between them).
You were absolutely on the right track, you simply stumbled over a little algebra toward the end.
You were absolutely correct up to and including the step where you said:
But then you treated as if it were a coefficient of rather than a separate term. Rather than saying is the reciprocal of , you needed to add to both sides of your equation, thus:
And finally you can write:

My calculator said it, I believe it, that settles it
