a) (3, 550) and (5, 1450)
b) (2, 300) and (20, 3500)
For (a), plug each point into the equation. This will give you:
This is a system of non-linear equations. What do you get if you divide the second equation (left-hand side by left-hand side, right-hand side by right-hand side) by the first equation? You should end up with something that you can solve for the value of 'b'. Then you can solve either of the equations for 'a'.
