My teacher gave us a problem. Part of it includes finding the slope.
The coordinates given are: (T,1) and (T/2,0).
I got y=((1-0)/(T-(T/2)))x-1
Another answer is y=(2/T)x-1.
Why Does 2/T = (1)/(T-(T/2))...?
P.S. I'd make a graph to show you guys. But I don't know how you make a graph on this forum...
