Look carefully at the slopes. Let set the values right now: L=R, so put an R by it, M=S, so put an S by it, and N=T, so stick a T on that line N. The line that is represented by L and R has zero slope, it's a flat line. The line represented by M and S has a negative slope. The line represented by N and T has a positive slope. Therefore, T is greater than R, which is greater than S, or C.
