Think about what you've learned about whole numbers. then study the following sequence. what is the next letter in the sequence? o, t, t, f, f, s, s, ?

The next letter would be E. This is because O stands for one, T stands for two, T stands for three, F stands for four, F stands for five, S stands for six, S stands for seven, now E stands for eight and so on.

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
