## anonymous one year ago tell me everything about slope intercept please

• This Question is Open
1. pooja195

y=mx+b m=slope b=y-intercept congrats now you know

2. anonymous

i need to know how to solve things like:What is the slope of the equation 3y = 9 - x, note: i am NOT looking for a answer, i want a solution on how to find the answer please

3. pooja195

to isolate y u need to divide everything by 3 $\huge~\rm~\frac{ 3y=-x+9 }{ 3~~~~~~~~~~3~~~~~3 }$

4. UsukiDoll

rearrange the equation into y = mx+b and then divide everything by 3 like what @pooja195 mention.

5. pooja195

i just flipeped the equation a bit to make it easier for u :)

hi

slope is the change in vertical distance per every horizontal distance

12. dan815

do u get what slope is now?

13. dan815

slope tells you the change in height for 1 unit change in x

we dont care what points we pick on the line, because that proportion will always be the same

16. dan815

as they are all similar triangles along this line

im starting to get the hang of it! what youre drawing is like what this chick is saying in this video http://www.virtualnerd.com/tutorials/?id=PreAlg_08_01_0005 im getting the hang of it, but when it comes to questions like: What is the slope of the equation 3y = 9 - x, i dont know how to solve that

20. dan815

ok ya, watch videos and stuff thats good

oops its x=0 for the b

23. anonymous

thanks @dan815 ! ima look at what you have drawn for me, and same to you @saseal!

also bear in mind regard the x-axis in the independent axis and y-axis is the dependent axis.
