From your info in the problem, two ordered pairs that would be on this line, assuming that it IS a line, would be (0, 32) which means that when she sat down (time spent typing is 0), she already had 32 words down.  The next pair is (30, 896) which means that at time 30 minutes, she had 896 words.  I don't know what your answer choices are, but you could use those points to find the slope then write an equation using that slope and one of the points and then you could find the number of words at ANY time t.  That's what makes these equations such a beautiful thing to learn!
