The first thing you should do for this case is a function that suits the context of the problem.
 Let:
 x: number of days.
 y: number of fish trapped by melissa and Joe.
 The generic equation of the line is:
 y = mx + b
 Melisa catches 2 fish each day. Joe catches 4 fish each day. So:
 m = 6
 Today, both melissa and joe have no fish. So:
 b = 0
 In this case we have:
 y = 6x
 Looking at the graph we see that by day five, both have 30 fish.
 answer
 f (x) = 6x
 f (5) = 30
