Are you supposed to assume that the function y is linear or that it is quadratic?

                                              576-400
If linear, find the slope:  m = ------------- = 176
                                                 6-5

Then the equation you want is y-400 = 176(x-5), or
                                                 y         = 176x - 880 + 400, or y = 176 - 480.
