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?

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 :/

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 ?

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?
