Lets work with the first one.

OpenStudy (anonymous):

f(x) = -1x + 1

OpenStudy (anonymous):

To find the slope, we need two ordered pairs. Do you know how to find ordered pairs using this function?

OpenStudy (anonymous):

@jenniferjuice

OpenStudy (jenniferjuice):

i find the slope?

OpenStudy (anonymous):

You need to find ordered pairs in order to find the slope. But do you know how to find ordered pairs using this function?

OpenStudy (anonymous):

Yes or no, I won't judge you. :D

OpenStudy (jenniferjuice):

not really :/

OpenStudy (anonymous):

Okay that's fine, I'll teach you. :D

OpenStudy (anonymous):

f(x) = -1x + 1 We need to find x and y. f(x) = y, and y = f(x). You will need to remember that, because it's important.

OpenStudy (anonymous):

So we will choose an x value, what do you want it to be?

OpenStudy (anonymous):

@jenniferjuice , choose an x value. like x = ?

OpenStudy (jenniferjuice):

-1 ?

OpenStudy (jenniferjuice):

dont i just need to find the slope of g(x) ?

OpenStudy (anonymous):

You have to compare the slopes of f(x) and g(x).

OpenStudy (anonymous):

So, f(x) = -1x + 1 let x = -1 f(-1) = -1(-1) + 2 f(-1) = 1 + 2 f(-1) = 3 Now we replace f(x) with y y = 3 So when x = -1 y will = 3 so one ordered pair for this equation is (-1,3)

OpenStudy (anonymous):

Do you see how I did that or would you like me to go in depth so you can learn it more?

OpenStudy (anonymous):

@jenniferjuice

OpenStudy (anonymous):

I'd love to help you if you're still there. :D

OpenStudy (jenniferjuice):

sorry um

OpenStudy (jenniferjuice):

the slope of f(x) = -1 its given
