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

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?

What is 8*0?
anonymous
  • anonymous
0
anonymous
  • anonymous
y = 8*0 +1
anonymous
  • anonymous
oh...... i think i understand it. So my y-intercept would would equal 1
anonymous

Yup! :-)

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?
anonymous
  • anonymous
8
anonymous

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.
