Please help me with question 24. I don't understand why the answer is C. I tried to do it but I only got up to solving the equation of the linear line.

24 In the xy-plane, the graph of a linear equation of the form y = mx + b and the graph of an exponential equation of the form y = ab* both contain points (1, 3) and (2, 4). If the point (r, s) is on the graph of the linear equation and the point (r, t) is on the graph of the exponential equation, where 0 t, which of the following must be true? A) O
