The equation provided is good and you need now to sketch a graph, hence, you should write either g in terms of n, or n in terms of g such that:
`3g + 7n = 28`
`3g = 28 - 7n => g = (28-7n)/3` (write g in terms of n)
or
`3g + 7n = 28`
`7n = 28 - 3g => n = (28-3g)/7` (write n in terms of g)
You need to sketch the graph of the linear function `g = (28-7n)/3` such that:
You need to sketch the graph of the linear function `n = (28-3g)/7` such that:
Notice that the functions `n = (28-3g)/7` and `g = (28-7n)/3` are inverses to each other.
