dw:1360554027098:dw the domain for the first piece is 0≤x≤2 the equation for this interval is y=x the domain for the second piece is 2≤x the equation for the second piece is y=2

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

UnkleRhaukus Group TitleBest ResponseYou've already chosen the best response.2
um, you could find the equation of the line using the Twopoint formula, since you have at least two points

i thik thats what they want us to do.

do i get just any set of points?
 one year ago

UnkleRhaukus Group TitleBest ResponseYou've already chosen the best response.2
so you could use the points \((x_1,y_1)=(3,4)\) \((x_2,y_2)=(6,1)\) but you could choose different points on the line and you should get the same answer
