Graphing...
I am going ahead in my math book, and I completely forgot something... If you were to plot the graph Y=5/3sin(-2Pi/3)x+1, how would you do it? What do each of those numbers mean?

Maybe give some free advice about: School?
Deceivingly simple. -2π/3 is a scalar. Sin of that is a scalar. Multiple that, and it's still just a number. Sin of -2π/3 is negative sqrt(3)/2. Pays to know your unit circle.

I don't have a graphing calculator with me, but basically don't you just solve it. Do sin (5/3) times (-2*3.14/3). That will be your slope. So it will be y=(your answer)x+1.
hope this helps- :)
