Where is the y intercept?
OpenStudy (anonymous):
Your answer should come out to y = (slope)x + (y intercept)

So 4?

Yup! Now we need to find the slope. So far we have this:
y = (slope)x + 4
OpenStudy (anonymous):
Slope is expressed as\[\frac{ rise }{ run }\] and can be found my the difference of 2 points\[\frac{ y_1-y_2 }{ x_1-x_2 }\]
OpenStudy (anonymous):
To do this we just need to find two points of the line, we know that (0,4) is one and (1,-1) is one.
OpenStudy (anonymous):
-2, -2?
OpenStudy (anonymous):
(0,4) = (x_1,y_1)
(1,-1) = (x_2,y_2)

No it's 4
OpenStudy (anonymous):
You can see howover the course of 1 x the y goes up 4
OpenStudy (anonymous):
4 is your slope so your answer should look like
y = 4x + 4
OpenStudy (anonymous):
Ohhh I see. Thanks!!!!

Also can you check my answer for this.
When is the function constant?
from x = to x =

I got from x = 0 to x = 6
OpenStudy (anonymous):
Nope, when does it stop having the same pattern?
OpenStudy (anonymous):
You can see it flattens out at x=3 onword
OpenStudy (anonymous):
So it would be x=0 to x=3
