This looks like homework. There is a clearly-stated no-homework policy in the Posting Guide.
Some hints though (typing a question mark before a function name in the console shows the help file for that function): - Generate some x values (?seq) - Calculate y values using x - plot x against y (?plot) - fitting can be done many ways, but the most common is using the ?lm function to fit and the ?predict.lm function to obtain points on the fitted equation.
