=

OpenStudy (wolfe8):

Again, rearrange it into the form I showed you last time.

OpenStudy (anonymous):

Do you know how to manipulate each of those to put them into the form: y = mx + b Isolate y on the left side for each of those...your slope will be the number next to the x

OpenStudy (wolfe8):

What did you just do lol. Rearrange all of them first. Show me.

OpenStudy (shamil98):

You don't have to rearrange them.. From standard form: \[\Huge Ax+By = C\] \[\Huge Slope = \frac{ -A }{ B }\]

OpenStudy (pixiedust1):

oh okay!

OpenStudy (wolfe8):

^Or you can do that one. Whichever is easier for you. But you might want to practice on your rearranging skill too.

OpenStudy (pixiedust1):

Okay, I'll rearrange. I had x+2y=0 -x from both sides 2y=0-x The divide both by 2 y=0/2-x/2

OpenStudy (shamil98):

yep

OpenStudy (shamil98):

just write it as y = -x/2 tho

OpenStudy (wolfe8):

Yup. And that is also -1/2x=mx where m is the gradient.

OpenStudy (pixiedust1):

Oh okay! And x=-1, right?

OpenStudy (wolfe8):

x is just x. What do you mean by that?

OpenStudy (pixiedust1):

x equals 1 here, since x/2 got to 1/2

OpenStudy (wolfe8):

You're not looking for x this time. You just want the gradient of the equation. And that is m, as I said in post.

OpenStudy (pixiedust1):

okay, thanks! have a nice day

OpenStudy (wolfe8):

You're welcome. So did you get it?

OpenStudy (pixiedust1):

yah :D
