Which is the slope and y-intercept of the following equation? y = 8x + 1
Do you know slope y -intercept formula?
Please look it up, so you can learn!
Paul is God. He got me through calculus, so I'm sure he can get you through algebra. Read through this whole section, you'll learn a lot. http://tutorial.math.lamar.edu/Classes/Alg/Lines.aspx

Chlor, you can still answer, I just wanted to pass on these notes. They are awesome.
thanks ill read these and see if they help
Just give me any idea about slope!
@ewokkman1, your y-intercept will be when x=0. Look at any graph and you can understand this visually. So plug x=0 into your equation and see what you get.
so the y-intercept will =9?
oh...... i think i understand it. So my y-intercept would would equal 1
And if you ever have it where it's not in y=mx+b form, first step is to always always always get it in that form. No coefficient next to the y. Make sure y is by itself. You'll understand more when you read through those notes, they explain it really well.
So what is "m" in your case?
Yep. And if you want to graph the line by starting at a given point, you want to move up 8 in the positive direction, and over 1 in the positive direction. They don't really specify this, but it's implied. m= 8/1 = 8. That helps if you don't feel like plugging in another point but just graphing the function. If it's -8, then that mean move down 8 in the negative direction and over 1 in the positive direction.
