Best ResponseYou've already chosen the best response.4so the equation...we have m= 0, and can figure out our "b" value by plugging everything we know into To figure out the "y" value, plug x=pi back into original equation. \[\large y=f(\pi) = \pi + \sin(\pi)\] what is your yvalue?

Best ResponseYou've already chosen the best response.4_ y = pi. now we have m =0, y = pi, x= pi. \[yy_{1}= m(xx_{1})\]\[y\pi = 0(x\pi)\]\[y=\pi\]
