Question

how do you find the y intercept and slope when y=8.5x-8?

Answer 1

This is in the form y=mx+c.
Remember that m is the gradient or slope, and c is the y intercept.
Can you work it out now? :)

Answer 2

so is this a LinReg ax+b test on my calculator?

Answer 3

I'm sorry, I have no idea what that is :S
But if you just need the slope and y intercept, you don't need a calculator!

Answer 4

ohh ok, so I still can't figure it out

Answer 5

Hm, what do you need to do?

Answer 6

can you step me through it?

Answer 7

What do you need?

Answer 8

ok so if y=Mx+C ...does that mean I do 8.5x+8?

Answer 9

You do that when you want to find out the value of y or x. If you want the slope and y intercept you don't need to do this.

y=mx+c m=slope c=y intercept
y=8.5x-8 m=8.5 c=-8

So the slope is 8.5, and the y intercept is -8 :)

Answer 10

ohh ok got it! THX!!!

Answer 11

Awesome! :) No problem!
