Initial value in the equation is the y-intercept
OpenStudy (ladylauren):
so -4 or -3
Mehek (mehek14):
\(y=\color{red}{m}x+\color{blue}{b}\)
m = slope
b = y-intercept
OpenStudy (ladylauren):
so how do you get the slope
Mehek (mehek14):
We don't need the slope

Mehek (mehek14):
Initial value = y-intercept = b = ?
OpenStudy (ladylauren):
i don't get that
Mehek (mehek14):
Ok
Initial value is the y-intercept
Mehek (mehek14):
The y-intercept is the "b" in the equation I put
\(y=\color{red}{m}x+\color{blue}{b}\)
Mehek (mehek14):
So in the equation you have, instead of b, what is the number?

OpenStudy (ladylauren):
would it be 4
OpenStudy (ladylauren):
or -4
Mehek (mehek14):
That is where the m is so it's the slope
Mehek (mehek14):
Anything attached to the variable can change so it is not the initial value
OpenStudy (ladylauren):
would it be 3 then

Yes
OpenStudy (ladylauren):
3 or -3
Mehek (mehek14):
-3
OpenStudy (ladylauren):
i don't know how to find if it is positive or negative
OpenStudy (ladylauren):
ok thx

If there's a negative before it, it's -
