solve for y. Once you have it in y=mx+b form the slope is m
Okay, thanks. So I'm trying to solve for y and put it in the other form?
rearrange the equation so it looks like y=mx+b ... you may need to do some division because we need y by itself.
What should I get when I do that? (this isn't a homework problem, I'm just finding practice problems to get more practice) I think if I see all the steps I may understand.
given: 16x+8y=192, we know that y = mx+b is the slope-intercept form so we need to rearrange 16x+8y=192 to make it look like y =mx+b so since the y portion needs to stay on the left what do we need to do to 16x?
that's later on.
16x+8y=192 but we need it in the form of y=mx+b . The 8y stays on the left.. so what do we need to do 16x... we need to _______ 16x to both sides
I am so sorry ... my typing went to the dogs tonight
Ohhhh that makes more sense! Oki, let me try it with this problem.
ok we now have our equation in y =mx+b form... 8y = -16x+192 so we divide the entire equation by 8. only the y portion of your answer is correct for the x portion, you forgot a negative sign the b value is wrong.
Oops, lost track of that negative!
wait nevermind the b is right
:P told ya I got sticky fingers my typing is off and I feel another migraine coming.. but yes everything was right except for the negative sign being dropped.
Ok. I'll have to watch out for that on my test, it's usually the little things that get me.
Thanks for the help guys!
