Best ResponseYou've already chosen the best response.2dw: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

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

Best ResponseYou've already chosen the best response.2the Twopoint formula\[yy_1=\frac{y_2y_1}{x_2x_1}(xx_1)\]

Best ResponseYou've already chosen the best response.0do i get just any set of points?

UnkleRhaukus

Best ResponseYou've already chosen the best response.2so 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
