Pre-Calculus scatter graph and linear model
A linear mathematical model for predicting prize winnings at a race is based on data
for 3 years. Create an example of such a model and then write a paragraph discussing the
potential accuracy or inaccuracy of it. (Need a scatter graph, linear model for the data, and
potential accuracy or inaccuracy of it)

The data will be represented with a set of ordered pairs. Where the first coordinate is the
number of the race and the second coordinate is the prize winnings in thousands of dollars.
Assuming that there are 4 races for year (one each three months) with a total of 12 races.
(1, 501) (2, 518) (3, 529) (4, 553) (5, 578) (6, 588)
(7, 602) (8, 616) (9, 622) (10, 655) (11, 674) (12, 683)
