ill give you a different example
|dw:1360553796475:dw|

combining \[y=\begin{cases}x&0≤x≤2\\2&2≤x\end{cases}\]

makes sense?

yes!! a million times yes!! let me work it out! thank you so much, about to give up.

can you help me with number 1 on my link above? just to know im doing it right?

what have you got so far?

for the first one i got \[f(x) = \left\{ 3 ; 0 \le x \le 3\right\}\]

and \[\left\{ x ; 3\le x \le 6 \right\}\]

what did you get for the equation of the second interval , y=x? thats not right

how?

i mean y=-x+7
the slope is -1
and the y- intercept would be at y=7

how did you get that thou/

|dw:1360558315458:dw|

|dw:1360558377826:dw|

|dw:1360558456267:dw|

\[y=mx+b=-x+7\]

OHHHHHH

is that the way to do it thou? or is there some equation/

how would i got about doing that?

i thik thats what they want us to do.

the Two-point formula\[y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\]

do i get just any set of points?

thank you!
